Question
A rectangular loop of wire with dimensions 1.88cm by 7.75cm and resistance 0.604? is being pulled to the right out of a region of uniform magnetic field. The magnetic field has magnitude 3.50T and is directed into the plane of the following figure(Figure 1) .
At the instant when the speed of the loop is 2.90m/s and it is still partially in the field region, what is the magnitude of the force the magnetic field exert on the loop?

At the instant when the speed of the loop is 2.90m/s and it is still partially in the field region, what is the magnitude of the force the magnetic field exert on the loop?Explanation / Answer
The required force to exert magnetic loop is
F = B^2 L v^2/R
=(3.5)^2(0.0188 m)(2.9)^2/0.604 =3.2 N
