A toroidal solenoid has an average radius of 14.09 cm and a cross sectional area of 0.928 cm2 . There are 1195 turns of wire on an iron core which has magnetic permeability of 4260 0 . The permeability of free space is 1.25664 106 N/A 2 . Calculate the current necessary to produce a magnetic flux of 0.000336 Wb through a cross section of the core. Answer in units of A.
