The magnetic field inside a superconductive magnet is 6T. The length of the coil body is l = 30cm and the diameter d = 2cm. The coil is made of 1km long cable of a superconductive Nb-Ti alloy and is found surrounded by liquid Helium (T=4.2K) and therefore in the superconductive phase.

a) Determine the number of windings

b) Determine the current in the coil

c) Determine the electrical Power required

Magnetic Field inside a Very Long Solenoid
The solenoid has length L, diameter D, and n turns per unit length with each carrying current .It is usual to assume that thecomponent of the current along the z axisis negligible.(This may be assured by winding two layers of closely spaced wiresthat spiral in opposite directions.)From symmetry considerations it is possible to show that farfrom the ends of the solenoid, the magnetic field isaxial.Which figure shows the loop that the must beused as the Ampèrean loop for finding Bz(r) for...
