A long solenoid magnet with radius R= 10cm designed for a fusion reactor is wound with super conducting niobium-tin (Nb3Sn) wire at a density of 180 turns per meter. The wire carries an a current of 30 kA. At a location far from either end, what is the magnetic field strength Bin in the solenoid? What is the magnetic field strength Bout outside the solenoid? The windings are themselves are subjected to a field 1/2 (Bin+Bout). What is the outward pressure on the windings?
