They were predicted by Maxwell, who also showed that c=1√μ0ϵ0, where mu0 is the permeability of free space and ϵ0 is the permitivity of free space. Maxwell’s prediction of electromagnetic waves resulted from his formulation of a complete and symmetric theory of electricity and magnetism, known as Maxwell’s equations.

Field strength is proportional to the line density. Field lines cannot cross. Field lines are continuous loops.

(a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet. (Recall that the Earth’s north magnetic pole is really a south pole in terms of definitions of poles on a bar magnet.) (b) Connecting the arrows gives continuous magn…
