Current Static Both 6/28 When can negative charges move from one object to another? Anytime two objects rub together or touch Anytime they touch they stick together Never 7/28 What two things does every circuit have? Negative Charge Positive Charge An unbroken path and a power source. 8/28 When electrical charges build up on the surface of an object, (BLANK) electricity occurs series current static 9/28 Push or pull conductor force insulator 10/28 A circuit that has only one path is a (BLANK) circuit Series static current 11/28 Where is a magnet's magnetism the strongest? Towards the North and South parts of the poles. Between the electrical current At the poles of the magnets. 12/28 The continuous flow of negative charges through a material is called (BLANK) electricity. current series attract 13/28 The pushing or pulling force caused by a magnet Hint: 2 choices magnetic flow magnetic field electromagnet magnetism magnetic flows magnetic fields electromagnets magnetisms 14/28 What are the two kinds of charges that particles of matter can have? Positive Negative Both 15/28 An unbroken path through path through which negative charges can flow insulator conductor circuit 16/28 A circuit that has more than one path is a (BLANK) circuit Neutral Parallel horizontal 17/28 An object that is able to attract iron magnet electromagnet magnetic field 18/28 A material that does not allow electricity to flow through it force resistor circuit insulator 19/28 Name two things that are not attracted to a magnet? Hint: 2 choices Paper Sand Wood Metal Coins 20/28 Magnets have a (BLANK) pole and a (BLANK) pole South and North West and East North and South East and West 21/28 Objects that have the same number of positive and negative charges are? Parallel Neutral Static 22/28 Name two things that use electromagnets? They could be stronger or weaker Fire alarms and telephones Cats and Dogs 23/28 As a (BLANK) flows through a circuit, it causes a magnetic field T Current Electric current flow water 24/28 What are two ways magnets can be used to produce electricity? By moving a magnet through a coil of wire and by moving a coil of wire you can use wires through a magnetic field. By moving a magnet current through a coil of wire and by moving a coil of wire you can use wires through a electric current. By moving a field through a coil of wire and by moving a coil of wire you can use wires through a water current. 25/28 Objects with the same kind of charge (BLANK) each other Repel Attract Neutral 26/28 A material that allows electricity to flow through it easily resistor conductor force 27/28 A temporary magnet formed when electric current flows through a wire coiled around a metal core Hint: 2 choices magnet generator electromagnet magnetism magnets generators electromagnets magnetisms 28/28 Objects with opposite charges (BLANK) each other Repel Attract Neutral
