A toroidal solenoid has a radius of 10.0 cm and a cross-sectional area of 0.500cm2 a) How many turns does the solenoid have if its inductance is 0.100 mH? b) What is the resistance of the solenoid if the wire being wound has a resistance per unit length of 0.0860 Q/ m? Now a current of 70 A is passed through the solenoid. Calculate: c) the magnetic field of the solenoid. d) the energy density of the magnetic field if the solenoid is filled with air. e) the total energy contained in the magnetic field of the coil (assume that the field is uniform)
