Question

A conductor is moving with a speed of 10m/s perpendicular to the direction of magnetic field of induction 0.5T. if the induced emf is 5V. Then length of conductor is

Answer 1

Answer:

Length of conductor is 1m

Explanation:

Induced emf = Blvsin

Where,  is angle made between velocity of conductor and magnetic field.

Here, B = 0.5T , induced emf = 5 volts and velocity of conductor, v = 10 m/s

So, 5 = 0.5 × l × 10 sin90°

l = 1m
