Figure 2

This is a common representation of electromagnetic waves. They are particular solutions of Maxwell’s equations, but in practice they occur only for radio waves and higher frequencies. In proximity to power lines and appliances, where only static or low-frequency currents or voltages occur, the electric and magnetic fields do not follow the characteristics given in this figure.
