Question:medium
A circular coil of radius 10cm with 200 turns is placed $\perp$r to uniform magnetic field of 1.4T. IF magnetic field reduced to zero in 0.2s, what is the average induced emf
A circular coil of radius 10cm with 200 turns is placed $\perp$r to uniform magnetic field of 1.4T. IF magnetic field reduced to zero in 0.2s, what is the average induced emf
Show Hint
"Placed perpendicular to uniform magnetic field" means the plane of the coil is perpendicular to the B-field lines. This makes the area vector parallel to the field lines ($\theta = 0^\circ$), giving maximum flux $\Phi = BA$.
