A coil of wire has 3000 turns and a radius of 1.5m. The wire
itself has cross-secional area of 0.004m^2 and a resistivity of 2.8
*10 ^ (-8) Ohmm.
If a magnetic field of 1.7T needs to be created at the center of
the coil, what is the potential difference that needs to be applied
to each end of the coil?
