I have a question as part of my assignment and need some guidance, any help would be appreciated
apporeciated
Part 1-
Derive and calculate the magnetic flux density in the core of a solenoid of length 30.48 cm that has n = 5000 turns of wire wrapped around a ferrite core, with a current of I = 500 mA passing through the coil. Assume the ferrite rod core has a radius of a = 10 mm and a relative permeability of μr = 6000

Part 2 - Calculate the self-inductance of this solenoid

Part 3 - Calculate the magnetic flux density at z = d/2 and z = 0 for the above solenoid if the length is reduced by a factor of 10.
