In case of a uniform magnetic field, the lines of magnetic induction are

A square loop of edge a has N turns and a total resistance R . The loop moves with constant velocity v through a region of constant magnetic field B . The loop enters in magnetic field at t=0 . Discuss the vartion of (a) Flux passing through the loop (b) the induced emf and (c) the external force acting on the loop a function of position of the loop in the field.

In which of the following cases the emf is induced due to time varying magnetic feld (induced field emf)? Case I A magnet is moving along the axis of a conducting coil Case II A loop having varying area (due to moving jumper) is placed in a magnetic field case III The resistance of the coil is changing, which is connected to an ideal battery. case IV a current carrying wire is approaching a conducting ring.

Where is the gravitational field zero and where is the gravitational potential zero, in case of Earth?

y = In (1-x^(2))/(1+x^(2)) find d^(2)y if : (a)x is an independent variable, (b) x is a function of another variable. Consider the particular case when x = tan t

A region of width L contains a uniform magnetic field B directed into the plane of the figure. A square conducing loop of side length l ( lt L) is kept with its side AB at the boundary of the field region (see Figure). The loop is pushed into the field region with a speed such that it just manages to exit the field region. Calculate the time needed for the entire loop to enter the field region after it is pushed. Mass and resistance of the loop is M and R respectively.
