Electricity and Magnetism By David Malec Static Electricity Static Electricity is made when charges build up. Static Electricity happens when objects have opposite charges. Static Electricity has two kinds of charges. Making Circuits There are two kinds of circuits one is a Series circuit and the other is a Parallel. A circuit is made when an electricity source is connected to wire which makes a path for the electricity to follow. Magnetic Poles A magnetic pole is the end of a magnet. There is a North Pole and a South Pole. Opposite magnetic poles attract and poles that are alike repel. Magnetic Fields The shape of the field depends on the shape of the magnet. The field loops around the magnet differently depending on what it is doing. The magnetic field attracts any type of metal or steel objects near it. Electromagnets An electromagnet is made when a magnet that has coils of current carrying a wire around an iron core. An electromagnet is a temporary magnet. It has a magnetic force only when it has an electric current passes through the wire coil. Electrical Energy We use electrical energy to light up our houses, heat up objects, and to power objects that require it. We have used electrical energy since 1879 when it was created by Tomas Edison. Today we take electricity for granted so we have a lot of it.
