A conducintg circular loop having a redius of 5.0cm, is placed perpendicular to a magnetic field of 0.50 T. It is removed from the field in 0.50 s. Find the average emf produced In the loop during this time.

Text Solution

Verified by Experts

The magnetic flux `phi_(B)=BA=Bxxpir^(2)`
The induced emf `|e|=(Delta phi_(B))/(Deltat)=(Bxxpir^(2))/(Deltat)`
`=(0.50xxpi(0.05)^(2))/0.50`
`=7.85xx10^(-2)V`
