Summary of Magnetism Problems Practice Problems

Determine the electric and magnetic fields at the surface of a cylindrical conductor with diameter d, length = 10d, and conductivity σ, when there is current I passing through it. Assume a uniform electric field throughout, including at the surface of the conductor.

Determine the force that is exerted on a car that has a net charge of 500 μC and moves at a speed of 80 m/s perpendicular to Earth’s magnetic field which is 5.0 x 10⁻⁵ T.
