A sphere is centered at the origin with radius 3m. It has a total charge of 100 micro-Coulombs spread uniformly over its surface and is spinning with 3600 revolutions per minute.
1. What is the magnitude and direction of the magnetic field inside the sphere?
2. Given the magnetic vector potential (see in attachment), find the magnetic field at position r=<4,6,8>m© BrainMass Inc. brainmass.com October 10, 2019, 7:04 am ad1c9bdddf
This solution estimates a point outside and inside the sphere, where a magnetic field due to a rotating sphere is uniformly charged on the surface.
