Asolenoid with 625 loops, each with area 4.34*10^-4 m^2, is originally parallel to a 0.225 t magnetic field. in 0.166 s, it is rotated until it is perpendicular to the field. how much emf is generated? (unit volts)

EMF, E = 0.061 volts

Explanation:

It is given that,

Number of loops in a solenoid, N = 625

Area of the loop,

Magnetic field, B = 0.225 T

It is rotated until it is perpendicular to the field for 0.166 seconds. We need to find the EMF generated in the solenoid. The induced emf is given by :

When the solenoid is parallel, , E = 0

When the solenoid is perpendicular to the field, E = NBA

E = 0.061 volts

So, the generated EMF is 0.061 volts. Hence, this is the required solution.
