Electricity and Magnetism
Chapter 5
Graphic organizer foru electromagnetism An organizer to represent how an electromagnet works. | A Map on Electricity This map shows how electricity works. | Chart on Electricity This chart shows how many things we use that have electricity in them. |
A Picture Graph of Electricity This is a picture graph of the reaction when a outlet is having a plug put in it. | Alternating current An electric current in which electrons move rapidly back and forth. | Ampres A measure of the amount of current in a wire. |
Atoms The smallest parts of an element. | Charge The property of matter that causes it to be electrically positive or negative, caused by losing or gaining electrons. | Circuit A closed path along which an electric current travels. |
Conductors Materials, usually metals, that transmit electricity. | Direct current An electric current in which electrons move in one direction. | Electric currents The movement of electrons through matter. |
Electricity A form of energy made when tiny parts move around in an atom; energy that can power many devices. | Electromagnet A magnet that can be turned on or off and is made by sending electricity through metal. | Electromagnetism A combined force of electricity and magnetism. |
Electrons Particles in an atom that orbit the nucleus and have a negative electrical charge. | Insulators Materials, such as rubber and plastic, that do not transmit electricity. | Ion An atom that has gained or lost electrons and has an electrical charge |
Magnetic field An area around a magnet where magnetic force can be felt. | Magnetism A force that pushes and pulls certain metals. | Neutrons Particles in the nucleus of an atom that have no electrical charge. |
Protons Particles in the nucleus of an atom that have a positive electrical charge. | Static electricity Electricity caused by a build up of negative charges in one place positive charges in another. | Volts A measure of the amount of push that gets an electric current moving. |
Watt A measure of the rate at which electrical energy is being used. | Forms of Electricity Wind turbines are a form of electricity. Wind turbines are a form of wind energy. | Forms of Electricity Lightning is a form of electricity. Lightning is a source of static electricity |
