Michael Faraday discovered the law of electromagnetic induction in 1831. He realized that current in a circuit can be induced by changing the magnetic field. Faraday tested it by wrapping a paper cylinder with a wire and connecting the coil to a galvanometer.
Faraday then moved the magnet back and forth inside the cylinder. This discovery formed the basis of the adoption of electricity as a new technology. It is the foundational discovery behind the workings of electrical motors, transformers, generators and inductors. Faraday also came up with terminology relating to the study of electricity, such as electrode, cathode and ion.Learn More

Linus Pauling worked out the properties of chemical and molecular bonds. This helped him discover and verify the structure of the alpha helix, a secondary structure in many proteins. The alpha helix led him to discover the DNA genetic molecule and outline the three-dimensional structure of the DNA helix.Full Answer >
You can make a Faraday cage by taking a metal can and padding the interior with insulators like foam and cardboard. Wrap your electronic devices in foil before storing them inside the can. Pad the top with more foam, and seal the can using a lid and some metal foil tape.Full Answer >
