A magnetic B field of strength 10 T is perpendicular to a conducting loop of wire measuring 0.5 square meters with 50 turns. If the B field is linearly reduced to zero in 2 s, then what is the magnitude of the induced emf voltage

The magnitude of the induced emf is 2.5 volts.

Explanation:

Given that,

The strength of the magnetic field, B = 10 T

Area of the wire,

Number of turns in the conducting loop, N = 50

The magnetic field is linearly reduced to zero in 2 s. We need to find the magnitude of the induced emf voltage. Here, an emf will be induced due to the change in magnetic field. It is given by :

So, the magnitude of the induced emf is 2.5 volts. Hence, this is the required solution.

double the distance = divide strength by 4
