A 1000-turns coil encloses a rectangular area of dimensions 35.0 cm and 25.0 cm. The coil lies in the plane of the page and carries a clockwise current of 4.7 A, as shown in figure below. If a uniform magnetic field of 180 µT is directed toward the left of the page, what is the magnitude of the torque of the coil? In which direction will the coil rotate?
Why does the number of loops on a copper wire effect the magnetic force?
a rod of m=4kg rests on two parallel rails that are L= .8m apart. Then we turn on the current, so the rod carries a current going between the rails (bottom to top in the figure, into the page) with a magnitude of I=2A. A uniform magnetic field of magnitude B=1.5 T pointing downward. I found final velocity to be 1.732 m/s. How long does it take to reach this velocity. Also, don't bother finding the force, I found this also.
