THE ROTATION OF MAGNETIC FIELD

The question I asked and searched for an answer is: Does the Earth's magnetic field rotate with the planet?

Many of you will say, of course it does. But beware, before you make quick conclusions. Some findings and facts explained on this site may be new to you. So come along with me in finding an answer to this simple question.

In 1832 famous scientist Michael Faraday performed some very interesting experiments with magnets and conducting disks. Since then in most schools teachers speak of these important experiments, which started the modern era of electricity, communication and Internet. Without Faraday's discovery of electromagnetic induction, none of this would be here now.

But! It took me years before I realised, that teachers in school did tell me but just a fragment of truth about this experiments. Why?

There is one experiment that Michael performed that puzzled him and everyone in scientific community since then. It is even today called Faraday's paradox. And teachers do avoid this subject, if they know about it, for it is rather puzzling to explain.

Let us repeat those Faraday's experiments. Since seeing is believing I suggest you do the experiments yourself. It is very easy. And takes just simple materials and instruments as permanent magnet, metallic disk, and voltmeter, drilling machine. A nylon string, glue, stick, and some adhesive tape.

Let us do the experiments.

We are all very familiar with the fact that a voltage is induced in conductor moving in magnetic field.

There are three experiments need to be done at first step.

1. Experiment
Take a permanent magnet and put it on table. Than take a metallic disk. Any conducting disk is fine. Attached this disk to some sort of rotating mechanism. You will need some sort of axes thru the centre of disk. I usually do this by attaching a metallic disk to some stick or short round bar with the glue. With for the glue to dry. Then put one end of the bar or stick in drilling machine. Now, you can rotate the disk around its axis.
Put the disk over the magnet, so that the axis of magnetic field of permanent magnet and the axis of rotation of disk coincide.
Rotate the disk over the magnet and measure the voltage between the rim and the axis of the disk. Induced voltage will be detected.
2. Experiment
Now you have to reverse rotating object. In this experiment you will have to rotate the magnet and have the disk stationary. Prepare the magnet as you did prepare the disk in experiment 1. Then put the magnet over disk so that the axis of magnetic field of permanent magnet and the axis of disk coincide. Now rotate the disk.
One would expect that the induced voltage would be measured. Yet it is not so. No voltage is induced in the disk. Even that you apparently have a relative motion between the magnetic field and the conductive disk.
3. Experiment
Let us make third and last experiment. Glue together magnet and conductive disk. Of course the axis have to coincide. And rotate them both. An induced voltage is measured between rim of the disc and it's axis. Yet there is no relative motion between magnet and the disk.

These three experiments performed by Michael Faraday were puzzling. Why?

There are two possible explanations of the phenomena. We know that if we have a relative motion between the conductor and magnetic field, voltage is induced in conductor. But these three experiments suggest something different. So we have two possible explanations. Keep in mind that we have actually three elements in these experiments. And we have to take in consideration relative motion between all three elements. Yet we have three experiments with three observed facts. So a definitive conclusion cannot be made.

First possible explanation is that in exp1 voltage is induced in disk, while we do not have relative motion between voltmeter and magnet. In exp2 voltage is not induced in disk and voltmeter. Yet both voltages are of same sign so the voltage difference cannot be measured. And in exp3 voltage is induced in voltmeter, because it has relative motion to magnet, while disk does not.

And there is also another possible explanation. The magnetic field cannot be rotated around its magnetical axis. We can rotate the magnet as much as we want, yet all we do rotate is the magnet not its magnetic field. In fact we must conclude that magnet does create or bear magnetic field. But we must also state that magnetic field and magnet are not one and the same reality. Like the colour of the ball. One red ball has it's own colour. And colour is a property of the ball. Yet if you rotate the ball, do you rotate the colour? Can you rotate or move the property of the object with the object? Everyone in right mind knows that the question does not make sense and cannot be answered.

But this did not satisfy me. I needed answer to this puzzle. And it was horrible revelation to me that some prominent 'scientist' tried to answer the question by repeating and repeating the same three experiments in well equipped laboratories, tried to measure some difference. It should be simple known to anyone that we have a riddle of three elements and three results. It cannot be solved like that. Even more saddening is the fact that this very same people used very complicated mathematical formulas to support one or the other answer. Yet it looks to me that they know how to calculate, they lack simple logic.

Like in all good things in life simple questions require simple solutions. I wasted a lot of time myself thinking of this Faraday's riddle. But after some time a solution to the question was formed in my mind.

The key question here is the relativity of conductor and magnetic field. So we have to dispense one element to gain conclusive decision. In our case this has to be measuring instrument, voltmeter. But by such constitution we have no longer ability to detect the presence of induced voltage. Or..?

Here I used the reality. We can never have a perfect disk with perfect roundness or a perfectly uniform magnetic field. And we can never put disk and magnetic filed perfectly in line of the same axis. This fact can be used in our new experiment. Let us do two more experiments.

1. Suspend the disk over the magnet on thin string, so that disk can be spinned over the magnet and that it can move of the vertical axis. Now spin the disk. It can be done by simply twisting the string. You will observe that after some time, disk tends to escape the magnetic field. It will start to spin around the magnet. Off the vertical axis. Reason for this is obvious. There are induced voltages in the disk. This produces eddy currents in the disk. The current as we know produces it's own magnetic field, that is just inverse of induced current. In perfect world with perfectly uniform magnetic field, conductor and mathematically exact position of both axes in the same line, all induced currents in the disk would be same. And they resultant of them would be null. Also the resultant of Biort Savart force between original on induced magnetic field would be null. Yet we live in imperfect world. So we can see by change in the position of rotating disk according to vertical axis the fact that voltage is indeed induced in the disk. As we would expect.
2. Now. For second experiment. Do not change anything. Make sure, disk is in its rest position and that it can spin and deflect form vertical axis freely. Now spin the magnet. If the magnetic field would spin on it's magnetic axis with the magnet, the same effect should be observed.
It is not so. The disk neither spins neither is deflected form vertical axis. And we have the same imperfection of elements and positions as before.

By this simple experiment I solved Faraday's riddle in December 2002. The magnetic field CANNOT BE ROTATED ON ITS POLAR AXIS.

I know many experiments were done on Faraday's paradox. Some even solved the problem. But none of these experiments were simple to perform and were not so conclusive as mine. And I do not know of anyone who did the same experiment as I did.

Now let us come to the basic question.

Does the Earth's magnetic field rotate with the planet?

If the magnetic field of simple permanent magnet is not rotated with the magnet? What about Earth's magnetic field. I mailed my discovery to some experts in the field of geomagnetism a month after my solution to Faraday's paradox. Most of them didn't reply. Some of them were not even aware of the existence of Faraday's paradox. I told you before, that teachers avoid the subject for lack of explanation. The rest concluded that Earth's magnetic field rotates with the planet in spite of fact that magnetic field of a simple magnet can not be rotated.

I will avoid repeating reasons they offered for their belief. Let us just say I never ever in my life heard of so stupid and ingenious claims.

One, best of them, to my opinion, was that Earth’s magnetic field is much more complex than magnetic field of bar magnet.

Is it?

I do not think that complexity of this planets magnetic field is simple. But as we all know even the smallest bar magnet has a magnetic filed that is just the result of many many small magnets constituting the bigger one. So even the smallest magnet is composed. One can find this simply by breaking the magnet. If you break the magnet you do not have separate poles. You have two magnets.

Obviously magnet is composed of many smaller magnets.

It should be noted here, that none of physics I know ever used simple but effective logic of Lucretius, by which he explained the existence of atoms. For if you can divide something, you must have the one that divides and the one between. This is just my hint to all people who still search for aether. J

Think. For our mind and logic is the best laboratory ever constructed. You do not need complex machinery to explore the nature and it's laws. All you need is clear mind, logic and a bit of fantasy. So if you can divide a magnet and the result is two magnets and two magnetic fields, you can question yourself, did you divide one magnetic field in two? And if so, what is that, that Lucretius would call »the one between«?

Fact is. This planet's magnetic field does not rotate with the planet. For even if it would be the most complex magnetic field in universe, it would still be obedient to the laws of nature. And the law of nature is that magnetic field cannot be rotated on it's own polar axis. Sic! Simple or complex. It does not rotate.

And if we accept this simple fact, we should know by now from all these simple experiments, that we do rotate in Earth's magnetic field, and some induced voltage must be present by that.

For all those scientist, who searched for reasons of telluric currents and explanations of geodynamo process that is creating Earth's magnetic field, please take this fact in consideration. It is of utmost importance. Feel free to forget all theories and hypothesis you know. Just perform these five simple experiments and conclude by your own mind and reason.

To me conclusive experiment is more than any even so beautiful theory. Facts are facts.

We do leave in sea of energy. Free energy. For if we would be able to construct a simple coil in which only one half would be sensitive to induction and other half noninductive, we could gain almost limitless quantities of electrical energy just from fact that we rotate and move in Earth's magnetic field.

Please do not confuse the rotation of magnetic poles around rotational axis of Earth. Earth's magnetic poles relation to any point on the globe does not change with the rotation of the planet. Position of poles rotate of course. But the magnetic field does not.

With these I conclude my first paper in the series of exploration. Feel free to e-mail me and comment these lines. But if in any doubt. Please do perform these experiment's yourself before you jump to conclusions and attack me for heresy.
