How much current is flowing in a wire 4.40 mm long if the maximum force on it is 0.575 NN when placed in a uniform 0.0550-TT field?

Current in wire will be equal to

Explanation:

We have given length of the wire l = 4.40 mm

Maximum force

Magnetic field B = 0.0550 T

We know that force on wire is given by

For maximum force value of will be maximum which is equal to 1

So force

So

So current in wire will be equal to

electrical power
