i solve my problem without ø=30°, I confused what this angle was used to do?
Electromagnetic induction is the process of generating an electric current by changing the magnetic field around a conductor.
Electromagnetic induction works by moving a magnet or changing the magnetic field around a conductor, which creates an electric current in the conductor.
Electromagnetic induction is used in generators to produce electricity, in transformers to change the voltage of electricity, and in induction heating to heat materials.
The amount of induced current in a conductor is affected by the strength of the magnetic field, the speed at which the magnetic field changes, and the number of turns in the conductor.
Faraday's law states that the induced electromotive force (EMF) in a closed circuit is equal to the rate of change of the magnetic flux through the circuit. This is the basic principle behind electromagnetic induction.
