Problem
James Clerk Maxwell's great contribution to electromagnetic theory was his idea that
(a) work is required to move a magnetic pole through a closed path surrounding a current.
(b) a time-changing electric field acts as a current and produces a magnetic field.
(c) the speed of light could be determined from simple electrostatic and magnetostatic experiments and finding the values of μ₀ and ε₀.
(d) the magnetic force on a moving charge particle is perpendicular to both its velocity and the magnetic field.
(e) magnetism could be explained in terms of circulating currents in atoms.
