Step-by-step solution

A point charge at rest produces only an electrostatic field in the surrounding space. A point charge moving with a constant velocity produces both electric and magnetic fields, but these fields do not vary with time in a way that generates electromagnetic waves. A steady current in a neutral straight wire produces only a magnetic field around it, as the net charge is zero. An oscillating point charge is an accelerated charge, which produces time-varying electric and magnetic fields that propagate through space as e
