Homework Statement
coils rotating in a magnetic field are often used to measure unknown magnetic fields. As an example, consider a coil of diameter 2.00 cm with 72.0 turns that is rotated about an axis perpendicular to the field at a rate of 20.0 Hz. If the maximum induced emf in the coil is...
Homework Statement
A wire with a weight per unit length of 0.040 N/m is suspended directly above a second wire. The top wire carries a current of 30.0 A and the bottom wire carries a current of 90.0 A. Find the distance of separation between the wires so that the top wire will be held in...
