    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?
    a. B=0

    2. Given the magnetic vector potential (see in attachment), find the magnetic field at position r=<4,6,8>m
