Eddy currents
When a magnet moves near a metal plate, Eddy currents appear. In the experiment, we study these currents and develop a contactless method to measure the thickness and conductivity of a metal plate.
Magnetism
Earth’s magnetic field
We measure the value and direction of Earth’s magnetic field, examining the oscillations of the magnetic needle.
Magnetic friction
We measure magnetic friction force for magnets depending on velocity and obtain the law of magnetic friction.
