Magnet oscilatin in coil
Magnets repelling each other, oscillate in the coil and the induced current.
Educational phase: motivation
- transparent plastic tube
- a small rod neodymium magnets
- connecting wires
Connect the voltmeter to the coil and if we move a magnet near the coil, we measure the induced voltage voltmeter. Voltage is positive or negative according to the direction in which moving magnet.
Electromagnetic induction is the phenomenon that occurs in non-stationary (unstable, changing) magnetic field. This magnetic field induced in the coil produces an electric field, which characterizes the induced electromotive force. When the coil is connected to power. circuit, it passes through the induced electric. flow. This Act deals with an electric voltage in a closed electrical circuit, which is caused by changing magnetic flux, which is known as electromagnetic induction: changing magnetic field around the coil in the coil induces electric. voltage in a closed circuit through the induced current. The direction of current is dependent on the direction of change of the magnetic field and the orientation of the poles of the magnet towards the coil.
