A loop of wire carrying current I (moving counterclockwise as seen from above) lies in the xy -plane. The loop is placed in a constant magnetic field of magnitude B that points at 30° from the z -axis. If the loop has a radius of 10 meters, carries a current of 2 amps, and the magnitude of the magnetic field is B Tesla, then the magnitude of the torque on the loop is given by AT Newton-meters What is the value of a if B = 10 Tesla?

A student makes a short electromagnet by winding 390 turns of wire around a wooden cylinder of diameter d = 4.1 cm. The coil is connected to a battery producing a current of 4.1A in the wire.

In the figure, two concentric circular loops of wire carrying current in the same direction lie in the same plane. Loop 1 has radius 1.70 cm and carries 4.40 mA. Loop 2 has radius 2.40 cm and carries 5.70 mA. Loop 2 is to be rotated about a diameter while the net magnetic field B set up by the two loops at their common center is measured. Through what angle must loop 2 be rotated so that the magnitude of the net field is 91.0 nT? Number i Units
