Question

Q:2
(a) A straight, horizontal length of copper wire has a current i =50A through it. What are the magnitude and direction of the minimum magnetic field needed to suspend the wire when the length of wire is 14cm and mass is 40g.
(b)There is a rectangular conducting coil, measuring 50cm by 25cm, with resistance 30ohm has 10 turns, as shown below. The coil moves at a constant speed of 100 cm/s from a region where the magnetic field is zero and into a region where the field is 4:00 T pointed along the
+z-axis.
N = 10
While the coil is in the process of entering the magnetic Field (and neither full in nor full out of the field):
(a) Determine the magnitude and direction (as viewed from above) of the induced current in the coil.(5) (b) Determine the magnitude and direction of the magnetic force that acts on the coil.(5)
