A steel wire of length 1.93 m with circular cross section must stretch no more than 0.240 cm when a tensile (stretching) force of 450 N is applied to each end of the wire.
What minimum diameter is required for the wire?
The second part of this question says only the circular section isrotated 90 degrees CCW. Therefore, shouldn't the magnetic fieldfrom the wire be in the k direction and the magnetic field from the loop be in the i direction? The net field should be a..
