Fig. 12.32 shows a long, rectangular, conducting loop of with l, mass m and resistance R placed partly in a perpendicular magnetic field B. With what velocity should it be pushed downwards so that it may continue to fall wihtout any acceleration?

Shows a horizontal magnetic field which is uniform above the dotted line and is zero below it. A long, rectangular, conducting loop of width L, mass m and resistance R is placed partly above and partly below the dotted line with the lower edge parallel to it . with what velocity should it be pushed downwards so that it may continue to fall without any acceleration?

The figure shows a rectangular conducting frame MNOP of resistance R placed partly in a perpendicular magnetic field vecB and moved with velocity vecV as shown in the figure. Obtain the expressions for the (a) force acting on the arm 'ON' and its direction, and (b) power required to move the frame to get a steady emf induced between the arms MN and PO.

Obtain the expressions for the (a) force acting on the arm 'ON' and its direction, and (b) power required to move the frame to get a steady emf induced between the arms MN and PO.

A conducting loop of cross-area A and resistance R is placed perpendicular to a magnetic field B . The loop is withdrawn completely from the field. The change, which flows through any cross-section of the wire in the process

As shown in the figure, a conducting rod of length I, mass m and resistance R falls through a magnetic field vecB in a plane perpendicular to plane of figure. Find terminal velocity of rod.

In Fig. 30-59, a long rectangular conducting loop, of width L , resistance R, and mass m, is hung in a horizontal, uniform magnetic field vecB that is directed into the page and that exists only above line aa. The loop is then dropped, during its fall , it accelerates until it reaches a certain terminal speed v_(t) . Ignoring air drag, find an expression for v_(t) .

A rectangular loop of resistance R, and sides l and X, is pulled out of a uniform magnetic field B with a for maintaining uniform velocity of withdrawal is __

A conducting circular loop of radius r carries a constant current i. It is placed in a uniform magnetic field B such that B is perpendicular to the plane of loop. What is the magnetic force acting on the loop?
