A piece of wire is bent to form a circle with radius.It has a steady current flowing through it in a counterclockwise direction as seen from thetop (looking in the negative direction).

What is $B_z(0)$ , the z component of at the center (i.e., $x = y = z = 0$ ) of the loop?

A long, vertical, straight wire carries a current I which isdirected upward. The wire is perpendicular to the plane of acircular metal loop and passes through the center of the loop. Theloop is allowed to fall and maintains its orientation with respectto the straight wire while doing so. In what direction does thecurrent induced in the loop flow?
a) There is no induced current
b) It is flowing around the loop in a counterclockwisemotion.
c) It is flowing in a clockwise motion.

A circular loop of wire with area A lies in the xy -plane. As viewed along the z -axis looking in the -z -direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field B is given by , where is a positive constant, and for this orientation of the loop the magnetic potential energy is negative. The magnitude of the magnetic field is .
