To make a strong uniform magnetic field, a superconducting solenoid is frequently employed. Once the current is "loaded" into the superconducting solenoid, the two ends can be tied together and then the current will continue to circulate forever. Calculate the inductance and the total energy stored in the following two superconducting magnets. Ignore the fields outside the magnets. (Part a) The strongest constant field that can be created with currently available laboratory equipment is . This field is created with a current of , inside a core with a diameter and an active length (where the field is basically uniform) of about . What is the inductance of the magnet, and the total energy stored
