A loop of radius R=5m encloses the magnetic field at t = 0 and then pulled at uniform speed v = 2 m/s In the plane of the paper. Find the induced emf (in V) in the loop at time t = 3 s.

A uniform magnetic field B = 0.5 T exists in a circular region of radius R = 5 m. A loop of radius R=5m encloses the magnetic field at t = 0 and then pulled at uniform speed v = 2 m/s In the plane of the paper. Find the induced emf (in V) in the loop at time t = 3 s.

an induced current is developed in it Some magnetic flux is changed from a coil of resistance 10Ω. As a result which varies with time as shown in figure. Find the magnitude of the change in flux through the coil in weber.
