... The changing-electric-creates-magnetic and changing-magnetic-creates-electric effects make possible electromagnetic waves (radio waves). These waves are usually emitted from a wire (antenna) connected to an oscillator (in essence, a battery that repeatedly reverses polarity very fast). The antenna r ...

... Notes to the Teacher The magnetic field around a currentcarrying wire forms concentric circles around the wire. The direction of the magnetic field is given by the “right-hand” rule: When the thumb of the right hand points in the direction of the conventional current, the fingers curl around the wir ...

... If a photon or electromagnetic radiation of the same frequency is applied to the electrons in the magnetic field, the spin of the electron will either flip. The flip is either from a lower energy spin to a higher energy spin or vice versa (stimulated transition). Electrical connections of experiment ...
