Electromagnetic Induction: Induced EMF in a rotating loop

1. A rectangular loop with surface area A lies in the x,y-plane with two sides parallel to the x-axis and the other two parallel to the y-axis in the presence of a uniform magnetic field with a magnitude B directed along the positive x-axis. The loop is made to rotate around an axis that is parallel to the y-axis and bisects the ...continues

Electromagnetic Induction: EMF in a ring outside a solenoid

A long solenoid is wound with 500 turns per meter and current in its windings is increasing at the rate of 100A/s. The Cross-sectional area of the solenoid is 4.0cm^2. If the solenoid is encircled at its center by a circular conducting loop, Find the magnitude of the induced electric field within the outside conduction loop if ...continues
