This is a strong, short-lived magnet created by a looped electrical current. a force of attraction/repulsion due to the spin of electrons. this is a machine that will convert mechanical, nuclear, or chemical energy into electrical energy. a propagating wave in space with electric and magnetic components. these components oscillate at right angles to each other. it may travel in a vacuum. this is a net gain or loss of electrons. this is a machine that converts electrical energy into mechanical energy. this is a flow of electrons that creates a charge, one of the fundamental forms of energy.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
