Question # 1

A glass rod of "L"Length is moving perpendicular to the applied magnetic field P with velociety v.Explain briefly about the induced emf in it.

Ans 1: Induced emf is zero.As glass rod is insulator and there are no free electrons to be shifted from one extreme to the other.Therefore there will be no effect of perpendicular magnetic field.The induced emf is only produced by moving a conductor across the magnetic field.

Question # 1

In a transformer there is no transfer of charge from the primary to the secondary.How is then the power transferred?

Ans 1: The power will be transferred because the two coils of transformer are magnetically linked i.e, the change of flux through one coil is linked with the other coil.

Question # 1

Name four methods to produce induce emf.

Ans 1: An induce emf is produced in the loop if the magnetic flux through it changes.The methods to produce induced emf are:
1. A bar magnet is moved towards the coil.
2. By changing the area of the coil in a constant magnetic field.
3. A coil of constant area is rotated in a constant magnetic field,
4. The coil is placed in the magnetic field of an electromagnet.
