a circular loop is pulled at a velocity v in plane of paper contaning magnetic field B?

Question

a uniform magnetic field of induction B(into the plane of paper) exists in a circular region of radius r. a loop of radius r encloses the magnetic field at t=0 and then pulled at a uniform speed v in the plane of the paper. find the direction of induced current and induced emf in the loop aqs a function of time?

Answer 1

The direction will be clockwise, and e.m.f will be BV √(4R² − v² t²)
