Learning about magnets When a magnet touches a nail, smaller metal pieces can be attracted to the nail, as shown in the picture. The nail itself becomes a magnet which causes the nail to become polarized. If you pull away the magnet, the nail loses some of its magnetization and will no longer exhibit as much attraction for other metal objects. If you touch a magnet to a piece of soft iron (iron with a low carbon content) replacing the nail, after you pull away the magnet, the iron loses all of its attraction for the other metal objects. This is because soft iron is a temporary magnet. Creating a Fruit Battery In this experiment, you will make a battery with fruits and learn about the principle of the wet cell battery. The chemistry behind the fruit cell is that zinc is more reactive than copper which means zinc loses electrons more easily than copper. As a result, oxidation occurs in the zinc metal strip and zinc metal loses electrons which then become zinc ions. The electrons then flow from the zinc strip to the copper strip through an external circuit. Making a Hand-crank Electric Generator In this experiment, you will make a hand-crank generator with an electric motor and learn about the working principle of electric generators. The electric generator, invented by Michael Faraday, converts mechanical energy to electrical energy. An electric generator consists of a number of wire loops placed in a strong magnetic field, which is similar to the electric motor. When the wire loops rotates, it cuts magnetic field lines. So the current is generated in a circuit. Building a Electric Raning Bell In this experiment, you will build an electric bell with batteries and a solenoid and learning the mechanics of the original ranging bell. When the switch is pressed, current flows around the circuit.
