What is the emf produced in a 1.5 meter wire moving at a speed of 6.2 meters/second perpendicular to a magnetic field of strength 3.96 × 10-3 newtons/amp·meter ?

Answer : The emf produced is, 0.0368 volt

Solution :

Formula used :

This equation is valid when B, l and v are mutually perpendicular to each other.

where,

B = magnetic field of strength =

l = length of wire = 1.5 m

v = velocity = 6.2 m/s

Now put all the given values in the above formula, we get the emf.

Therefore, the emf produced is, 0.0368 volt

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
