Expert Answer:

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

a) Electromagnetic induction is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field.

The reasons are,

Changing magnetic field, or

Changing area enclosed by the conductor loop,

Changing current.

b) The current carrying conductor will experience a force, when placed in a uniform magnetic field.

The force will be maximum when the direction of magnetic field is perpendicular to the direction of current.

And it'll be minimum when it's parallel.
