A conductuing loop having a capacitor is moving outward from the magnetic field. Which plate of the capacitor will be positive?

The magnetic field between the plates of a capacitor when r gt R is given by-

A bar magnet is quickly moved towards a conducting loop having a capacitor. Predict the polarity of the plates A and B of the capacitor.

A closed conducting loop moves normal to the electric field between the plates of a large capacitor. Is a current induced in the loop, when it is wholly inside the capacitor. The electric field is nromal to the plane of the loop.

In an oscillating L-C circuit the maximum charge on the capacitor is Q. What will be the charge on the plate of the capacitor, when energy stored in magnetic field and electric field are equal ?

A conducting loop having resistance R contains a capacitor of capacitance C. A uniform magnetic field B is applied perpendicular to the plane of the loop. The magnetic field is made to change with time as depicted in the graph [t_(0) = 2RC] . Plot the variation of charge on the capacitor as a function of time (t).

Answer the following quesitons : (a) A closed conducting loop moves normal to the electric fieldd between the plates of a large capacitor. Is a current induced in the loop when it is (i) wholly inside the capacitor (ii) partially outside the plates of capacitor. Electric field is normal to the plane of the loop. (b) A rectangular loop and a circular loop are moving out of a uniform magnetic field region to a field free region with a constant velocity, Fig. In which loop do you expact the induced e.m.f. to be constant during the passage out of the field region, the field is normal to the loops ? (c ) Predict the polarity of the capacitor in the situation described by Fig.
