The four wire loops shpwn figure have vertical edge lengths of either `L,2L` or `3L`. They will move with the same speed into a region of uniform magnetic field `vec(B)` directed out of the oage. Rank them according to the maximum magnitude of the induced emf greatest to least.

A

`1` and `2` tie, then `3` and `4` tie

B

`3` and `4` tie, then `1` and `2` tie

The figure shows four wire loops, with edge length of either L or 2L . All four loops will move through a region of uniform magnetic field vecB (directed out of the page) at the same constant velocity . Rank the four loops according to the maximum magnitude of the e.m.f. induced as they move through the field, greatest first

The following figure shows four wire loops, with edge lengths of either Lor 2L. All four loops will move through a region of uniform magnetic field B (directed out of the page) at the same constant velocity. (Corresponding to loop mentioned in Column II, information on induced emf is provided in Column I, match them correctly).

A square coil ACDE with its plane vertically is released from rest in a horizontal uniform magnetic field vec(B) of length 2L . The accelaration of the coilis

A rectangular loop of dimensions l & w and resistance R moves with constant velocity V to the right as shown in the figure. It continues to move with same speed through a region containing a uniform magnetic field B directed into the plane of the paper & extending a distance 3W . Sketch the flux, induced emf & external force acting on the loop as a function of the distance.

A straight wire of length L is bent into a semicircle. It is moved in a uniform magnetic field with speed v with diameter perpendicular to the field. The induced emf between the ends of the wire is

A thin wire of length L is made of an insulating material. The wire is bent to form a circular loop, and a positive charge q is distributed uniformly around the circumference of the loop. The loop is then set into rotation with angular speed omega around an axis through its centre. If the loop is in the region where there is a uniform magnetic field vec(B) directed parallel to the plane of the loop, calculate the magnitude of the magnetic torque on the loop.
