Question

(20 points) A 1200-turn solenoid of radius 2.00 cm and total length 16.0 cm has a 1.50 A current a. Find the magnetic field of the solenoid using Ampere's Law. integral.) b. A steel core is inserted into the solenoid. If the magnetic susceptibility of steel is 600, find the magnetization (M) and the total magnetic field of the solenoid. c. Assume each magnetic moment in the steel core is equal to one Bohr magneton, how many magnetic (You need to start from the Ampere's Law moments are there? d. If the current in the solenoid is changing at a rate of 12.0 A/s, what is the magnitude of the force exerted on an electron 3.00 cm from the axis of the solenoid? 2.00 cm 1200 turns 16.0 cm .00 c
