A square coil of resistance and side length is placed with its plane making an angle of with a uniform magnetic field of In the coil rotates until its plane becomes parallel to the magnetic filed. Find the current induced in the coil.
A rectangular loop of sides and with a small break in it is moving out of a region of uniform magnetic field of directed normal to the loop. What is the emf developed across the break if the velocity of the loop is in the direction normal to the longer side of the loop?
The magnetic flux through a coil of resistance placed with its plane perpendicular to a uniform magnetic field varies with time as Find the induced current in the coil at
A solenoid of diameter has turns per meter. At the center of this solenoid, a coil of turns is wrapped closely around it. If the current in the solenoid changes from zero to in what is the approximate induced emf developed in the coil?
A rectangular coil of turns and size is placed perpendicular to a magnetic field of Find the induced emf when the field drops to in
