what is Magnetism how it works
... The Chinese and Greeks knew about the “magical” properties of magnets. The ancient Greeks used a stone substance called “magnetite.” They discovered that the stone always pointed in the same direction. Later, stones of magnetite called “lodestones” were used in navigation. ...

Experiment 1: Thomson surrounded the cathode ray tube with a
... Thomson surrounded the cathode ray tube with a magnetic field and had sensors to measure small electrical charges (electrometers). The electrometers measured no change with magnets on the tube, indicating that the cathode rays had been bent by the magnetic field and therefore had negative charge. Di ...

Zeeman Effect
... Without a magnetic field, configurations a, b and c have the same energy, as do d, e and f. The presence of a magnetic field splits the energy levels. A line produced by a transition from a, b or c to d, e or f now will be several lines between different combinations of a, b, c and d, e, f. Not all ...
