Using standard notation, the complex form for the electric field that is polarised in the y-direction, and propagating near an observer along the x-axis from an radiating dipole is approximated by: E = E() exp[i(kx - wt)], where a is a constant, w is the angular frequency and E, gives the polar- isation of the wave. Find an expression for the associated magnetic field.
