Would like to know how to solve it. The magnetic field problem includes #'s 7,8,9,10,11© BrainMass Inc. brainmass.com March 4, 2021, 5:46 pm ad1c9bdddf
The way to proceed is sort of given to you. By breaking the problem up into 3 simpler problems, we can make the original problem easier.
The large cylinder has 2 small cylinders removed from it. We can represent the magnet fields from this new hollow cylinder as:
Magnetic field from 1 Large solid cylinder with positive current MINUS Magnetic field from 2 ...
With good explanations, the problem is calculated and solved.
