Consider a long solenoid that has n turns and is tightly wound using wire of diameter d. the radius of the solenoid is r. neglect fringe fields. (a) for a given current i, how big will the magnetic field in the solenoid be?
(b) a second solenoid is wound around the first one. the second solenoid has the same length as the first one, but uses wire that is twice as thick. what is the mutual inductance of the two solenoids? neglect fringe fields.
