ANSWER:

Solution 11P

a.)

Step 1 of 3

We have to calculate the induced emf in the circular wire loop.

The induced emf in the circular wire loop can be calculated using the expression,

     

where,

Area of the circular loop in m2

magnitude of change in the

       Magnetic field in T

s = 0.18 s
