Quick review - Electromagnetic Induction

The phenomenon of electromagnetic induction is :

• Producing induced current in a coil due to relative motion between a magnet and the coil.

• The process of rotating a coil of an electric motor.

• The process of charging a body.

• The process of generating magnetic field due to a current passing through a coil.

When the North-pole of a bar magnet is pushed towards the coil, the pointer in the galvanometer deflects, indicating the presence of __________ in the coil.   

• magnetic flux

• electric current

• voltage

  magnetic field

• magnetic field

When the North-pole of a bar magnet is pushed towards the coil, the direction of deflection of galvanometer needle gives the direction of ____________.

• force

• flow of current

• magnetic field

• voltage
