Lenz's Law simply explained - how it works

You need a horseshoe magnet.

For the two tests, with which the Lenz's Law is to be explained simply, you need three things: a voltmeter, a horseshoe magnet and a coil of copper wire.

So the Lenz's Law is simply explained

  1. Make the following experiment to: Have a horseshoe magnet vibrate at high frequencies, in the cavity of a coil. Watch on a device to measure voltage, what happens.
  2. They realize that you can create tension by using the magnets. This electrical voltage generated thanks magnet is called electromagnetic induction. At the respective ends of the coil causes induction voltage if the density changes of the field lines of the magnetic field in the coil.
  3. The induced voltage has a direction. This direction depends upon whether the magnetic field is reduced in the coil or enlarged.
  4. Replace in a second experiment, the voltmeter with a switch. Let the magnet again commute. Observe what happens when you leave the switch open and what happens when you close the switch.
  5. They note that the magnet in the case of the closed switch ceases to commute quickly and resting. Why causes the coil this braking? The oscillating magnet induces a voltage at the both ends of the coil.
  6. If the switch is closed, a current through the coil, by the wound copper wire flows. Because of the copper wire, the coil has only a small resistance. Therefore, the induced current can be relatively strong, which flows through the short circuited coil (i.e. with a closed switch).
  7. This current causes the coil turns to an electromagnet. What you can see now, is an "exciting" interaction. It takes place between two magnets from: between the horseshoe magnet and the electromagnet, which is caused by the induction current generated by you.
  8. Shuttling the north pole of the magnet in the coil, the magnet is only slowed down if, at the end facing the magnet of the coil also be north pole is formed. Then, when the north pole of the magnet also commutes back out of the coil, the pole must have reversed the electromagnet to the South Pole.

And so it has also been explained simply on the basis of two experiments that Lenz's Law. You can understand the Lenz's Law so already: An induction current is always directed so that it interferes with that process, which is the causative agent of the induction. This also explains why a perpetuum mobile is impossible.
