Answer 1

Answer:

N and S is the answer for this question

Answer 2

Induced EMF will be developed across the ends of the wire when it is moved towards P.

Reason:

• In order to get induced EMF , there has to be a change in electric flux according to Faraday's Law.

• Now , the magnetic field lines are directed from N pole to S pole of the magnet (in the figure).

• So, whenever the wire will be moved towards direction P , it will cut the magnetic field lines resulting in change in magnetic flux.

• This will cause induced EMF.

Let induced EMF be E ;

$\boxed{ \sf{E = \dfrac{d \phi}{dt} }}$
