Answer #1

Here,the length of the wire,

The velocity of the motion of wire,

the magnetic field caused by the solenoid,

Angle between the magnetic field and the velocity of the wire,

Here the magnetic field,length of wire and velocity are mutually perpendicular to each other.

We have the motional induced emf produced in the wire,

ie,induced motional emf,

ie,

Motional emf induced,
