... 3. that the two pieces of resin repel each other. These phenomena of attraction and repulsion are called electrical phenomena, and the bodies that exhibit them are said to be 'electrified', or to be 'charged with electricity'. Bodies may be electrified in many other ways, as well as by friction. Th ...

... After Oersted’s discovery, Andre-Marie Ampere performed extensive experiments and did an insightful mathematical analysis of the magnetic field induced around a current carrying wire. In addition, he studied the forces between current carrying wires. The induced magnetic fields around the wires inte ...
