((29.13))

A rectangular loop of wire with dimensions 1.84 cm by 7.57 cm and resistance 0.641 is being pulled to the right out of a region of uniform magnetic field. The magnetic field has magnitude 3.37 T and is directed into the plane of the following

Part A

At the instant when the speed of the loop is 3.09 m/s and it is still partially in the field region, what is the magnitude of the force the magnetic field exert on the loop?

Part B

What is the direction of the force the magnetic field exert on the loop?

Explanation / Answer

V=BLv
F=ILB=(BLv/R)LB
=L^2*B^2v/R

=0.0757^2*3.37^2*3.09/0.641

F=0.313 N
