- 3 An Infinitely Long Cylindrical Permanent Magnet With Radius A And Uniform Magnetization Parallel To Its Axis M 1 (30.49 KiB) Viewed 60 times
# 3.) An infinitely long cylindrical permanent magnet with radius a and uniform magnetization parallel to its axis, M = M2, is cut in half at the z = O plane. a. Find the magnetic fields B and H everywhere inside the magnet. b. The two halves are now separated by a small displacement in the z-direction, Az < a. Find the magnetic fields B and H everywhere inside the gap. c. What is the force between the two halves of the magnet? Hint: Recall that the magnetic energy density u = (1/2)B.H.
