Topics in Electricity and Magnetism
Magnetism and Magnetic Properties
- The first magnet was discovered nearly 5000 years ago in Magnesia.
- The word magnet is derived from the town name Magnesia.
- A magnet attracts small pieces of iron.
Electromagnetism and Electromagnets
- Hans Christian Oersted discovered in 1819 that there is a magnetic field around every wire carrying an electric current.
- A current-carrying cylindrical coil behaves like a magnet.
- A cylindrical coil is called a solenoid.
Electric Bell
- An electric bell is a common application of an electromagnet.
- The main parts are a horse-shoe electromagnet, a soft iron armature, a hammer, a gong, a metallic springy strip, an adjusting screw, a switch or bell push, and a battery.
- The armature is fixed to the metallic springy strip.
Electric Cells and Batteries
- A cell is a source of electricity.
- A cell consists of a vessel with two metal rods called electrodes and a chemical substance called electrolyte.
- In a simple cell, the copper rod becomes the positive electrode or anode and the zinc rod becomes the negative electrode or cathode.
Key Concepts
