(a) A loop of wire carries a conventional current of 0.6 amperes. The radius of the loop is 0.06 m. Calculate the magnitude of the magnetic field at a distance of 0.37 m along the axis of the loop, from the center of the loop.
(b) What would the magnitude of the magnetic field be at the same location if there were 100 loops of wire in a coil, instead of one loop?
