A Spinning Ball: What is the magnetic field inside and outside a uniformly charged solid ball (total charge ?, radius ?) spinning about its axis with angular velocity ? ̂?? Do this three ways:

(a) Set up a Biot-Savart-style integral to determine the field at any location. (Do not solve this integral, but make all quantities explicit.)

(b) Simplify your integral using a location along the axis of rotation: ? = ? ̂? or ? = 0. Solve for ? inside and outside.

(c) Use your result to determine where along the ? axis the magnetic field is the strongest.

Magnetic Field inside a Very Long Solenoid

The solenoid has length L, diameter D, and n turns per unit length with each carrying current .It is usual to assume that thecomponent of the current along the z axisis negligible.(This may be assured by winding two layers of closely spaced wiresthat spiral in opposite directions.)From symmetry considerations it is possible to show that farfrom the ends of the solenoid, the magnetic field isaxial.Which figure shows the loop that the must beused as the Ampèrean loop for finding Bz(r) for...
