Static electricity | the imbalance of positive or negative charges between objects |
electric current | the flow of an electric charge through a material |
resistance | a quality of an object which means that electric current cannot flow easily through it |
series circuit | a simple circular path in which an electric current flows only one way through each part of that circuit |
parallel circuits | two or more paths in which an electrical charge can flow |
magnetic field | the invisible force that loops between the poles of a magnet due to the arrangement of charges. The force is strongest at the poles, or ends, and get weaker as distance from the magnet increases. |
magnetism | the property of attraction of an object that has a magnetic field. It can attract other objects made of metal |
electromagnet | a coil of wire that causes a magnetic field when current moves through the wire |
