Question

Answer the following question:Be sure to show all work. Include formulae and units.Be sure to include relavant, meaningful diagram and a complete circuit diagram with circuit related problem. take enough space, don't try to squeeze everything on a small space!(problems are from:principle of physics:calculus based; Chapter: Magnetic forces and Magnetic field)

4.) A long straight wire carrying a current of 20 A.A rectangular loop of wire carries a clockwise current of 15 A.The dimensions of the loop are 0.2 m X 0.01 m, with the loop�s long dimension parallel to the wire as shown.The wire is in the same plane as the plane of the loop.The closest side of the loop is 0.5 cm from the wire.

What is the direction of the net magnetic force on the loop?

Answer 1

Here is the solution to the problem:

The net force is with direction to the left since the wire labeled 4 exerts a bigger force than the wire labeled 3 with respect to the long wire. This is because the dirrerences in distance.

NOTE: An upward direction was assumed for the long straight wire since it is not specified in the problem. If this

direction is wrong, the answer will have the same magnitude but in an opposite direction.
