A circuit ABCD is held perpendicular to the uniform magnetic field of B = 5 × 10^−2 T extending over the region PQRS and directed into the plane of the paper. The cicuit is moving out of the field at a uinform speed of 0.2 m/s for 1.5 s. During this time, the current in [...]

A gold rod of length l is accelerated in the horizontal direction with an accleration a0. The rod is held between two perfactly insulating clamps. Calculate the electric field set up in the rod. Take the mass of electron as m. An equilateral triangular loop ADC having some resistance is pulled with a constant velocity [...]

The linear loop has an area of 5×10^−4 m^2 and a resistance of 2 Ω. The larger circular loop is fixed and has a radius of 0.1m. Both the loops are concentric and coplanner. The smaller loop is rotated with an angular velocity ω rad/s about its diameter. The magnetic flux with the smaller loop [...]
