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.

A square loop of a conducting material of side l and resistance r is dragged through a uniform magnetic field B with uniform velocity v keeping the plane of the loop perpendicular to the direction of the field. What is the current flowing through the loop?

A square loop of side a and resistance R is moved in the region of uniform magnetic field B(loop remaining completely insidefield), with a velocity v through a distance x. The work done is:

Assertion If a loop is placed in a non-uniform (with respect to position) magnetic field, then induced emf is produced in the loop. Reason In a non-uniform magnetic field, magnetic flux passing through the loop will change. Therefore, induced emf is produced.

Through a uniform B field, A small rectangular loop is moving towards left with constant velocity as shown in the figure. Counting of time t begins at the moment, the loop starts entering the field. Plot the variation of flux through the loop with respect to time. Also, plot the variation of induced emf w.r.t. time t.

Initially there is no magnetic flux through a certain conducting loop. A magnetic field near the loop is then suddenly turned on, and 5 s later, the magnetic flux through the loop is 1.0 Tm^(2) . What is the average magnitude of the induced emf in the loop during those 5 s?
