If a magnet is put inside one coil of wire, a voltage is produced. what will happen if the magnet is put inside two coils of wire? a. there will not be a change. b. the voltage will decrease by a factor of two. c. the voltage will increase by a factor of two. d. the two coils of wire will cancel out the magnetic field. e. the voltage will be zero.

Respuesta :

When the magnet is put inside two coils of wire, the voltage will increase by a factor of two.

What is induced emf

An induced emf occurs when a magnet is placed in magnetic field and their is relative motion of a conductor placed in the magnetic field.

The strength of the induced emf increases with increase in the number of the turns of the conductor and its relative speed in the field.

emf = NdФ/dt

where;

  • N is number of the loops
  • dФ is change in magnetic flux
  • dt is change in time.

The above formula is the basis of Faraday's law of electromagnetic induction.

Thus, when the magnet is put inside two coils of wire, the voltage will increase by a factor of two.
