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

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
