Electric Circuits Electricity Atoms are made of three different particles, some have a positive charge, some have a negative charge, and some have no charge at all. Matter usually has the same number of positive and negative charges, making it neutral. Electricity is the flow of electrical charges. A simple circuit is a circuit in which an electric charge flows in only one path. Magnetism Magnetism is the property of attracting certain kinds of metals. The invisible field around a magnet is called a magnetic field. Magnets have two poles, a North end and a South end. Like poles repel each other while opposite poles attract; meaning the North pole on one magnet will attract the South pole on another magnet. Electromagnetism An electromagnet is a coil of wire through which an electric current passes. An electromagnet has a coil wrapped around an iron core. A parallel circuit has two or more paths the electric charge can flow through. If one bulb goes out, the other bulb will stay lit. A generator uses an electromagnet to turn mechanical energy into electrical energy by using the wind, falling water, and even steam. + - + - Static Electricity is the imbalance of positive or negative charges between objects. coils wire iron core switch current from battery + ALKALINE B A TTER Y Objects that have the same charge will repel each other.

A compass is a tool that has a small needle that responds to the Earth’s magnetic field by always pointing North. Magnetic Earth © Copyright NewPath Learning.
