Answer:

Induced emf in the coil, $\epsilon=4.05\ volts$

Explanation:

Given that.

Number of turns in the coil, N = 200

Side of square, d = 18 cm = 0.18 m

The field changes linearly from 0 to 0.50 T in 0.80 s.

To find,

The magnitude of the induced emf in the coil while the field is changing.

Solution,

We know that due to change in the magnetic field, an emf gets induced in the coil. The formula of induced emf is given by :

$\epsilon=\dfrac{d\phi}{dt}$

$\phi$ = magnetic flux

$\epsilon=-\dfrac{d(NBA)}{dt}$

A is the ares of square

$\epsilon=AN\dfrac{d(B)}{dt}$

$\epsilon=AN\dfrac{B_f-B_i}{t}$

$\epsilon=(0.18)^2\times 200 \times \dfrac{0.5-0}{0.8}$

$\epsilon=4.05\ volts$

So, the induced emf in the coil is 4.05 volts. Hence, this is the required solution.

Since Jim's speed is constant and he is moving in a straight line, he is not accelerating, and we know the net force on him is zero. There is no Force anywhere doing any work. So no power is being added to him or dissipated by him.
