E. M. Induction

1. The S.I unit of Magnetic flux is

• tesla

• oersted

• weber

• gauss

2. Due to relative motion of a magnet with respect to a coil,an emf is induced in the coil in accordance with

• Ampere's circuital law

• Faraday's laws

• Gauss's law

• Biot-Savart law

The direction of induced current is such that it opposes the cause which produces it.This is the law of

• Lenz

• Kirchhoff

• Fleming

• Biot-Savart

• -40 V

• 40 V

• 140 V

• 300 V

5. In Faraday's experiment on electromagnetic induction,more deflection will be shown by the Galvanometer when

• Magnet is in uniform motion towards the coil

• Magnet is in uniform motion away from the coil

• Magnet is in accelerated motion towards the coil

• Magnet is at rest towrads the coil

7. What is the unit of magnetic field strength?

• Tesla

• Oersted

• Weber

• Gauss

8. How does the induced current direction relate to the magnetic field change?

• It follows the direction of the magnetic field change

• It is perpendicular to the magnetic field change

• It opposes the magnetic field change

• It has no relation to the magnetic field change
