Assignment:
A uniformly charged hemispherical shell is rotating with angular speed ω about its symmetry axis as shown. Use the Biot-Savart Law to find the magnetic field at the center of the sphere (point P). Begin by discussing the direction of B→ . You may not use any results for the magnetic field due to any current configuration. Be sure to explain each step in your reasoning carefully.
Provide complete and step by step solution for the question and show calculations and use formulas.
