Answer:
Part a)
Part b)
Since the radius is decreasing so induced current will increase the flux through the coil
So it would be clockwise in direction
Explanation:
As we know that magnetic flux linked with the coil is given as
now the rate of change in flux is given as
now we know that circumference is decreasing at rate of 15 cm/s
so here we know the length of circumference as
So rate of change in circumference is
final length of circumference at t = 8 s
Part a)
Now the induced EMF is given as
Part b)
Since the radius is decreasing so induced current will increase the flux through the coil
So it would be clockwise in direction
