Last One Standing Rules 1. Two teams: 2 front rows/2 back rows 2. Sit on the table in silence (If you talk you are OUT) 3. Each person receives a question, correct answers stay up, wrong answers sit down. 4. Team with most players still up at the end wins (3 Extra Credit points on the test) READY . Any object that attracts Iron or objects made of iron. Magnet The push and pull bewtween two magnets • Magnetic Force The North (+) and South (-) ends of magnets • Magnetic Poles The area surrounding the magnet, where the magnetic forces can be detected • Magnetic Field The force produced when the opposite Poles of magnets coming close. • Attraction Materials such as iron, nickel, and cobalt that can be turning into magnets • Ferromagnets An iron core wrapped with electrical wire to create a powerful magnetic force. • Electromagnet The North pole of the Earth interact with the air charging particled called. • Aurora (Aurora Borealis) The relationship between magnets and electricity • Electromagnetism The coil of wires that carry an electrical current to produce a mangnetic field. • Solenoid A device used to measure the electrical strength and direction. • Galvanometer A machine that uses magnetic force to see inside the body. • MRI A device that transferse electrical energy into mechanical energy. • Electric Motor Using a magnetic force to create an electrical current in a wire. • Generator A device that uses electromagnetic induction to increase or decrease the voltage of an alternating current. • Transformer A _________________ uses electromagnetism to look inside the body. • MRI Increasing the number of loops or electrical current in this will increase the strength of the magnetic field. • Solenoid An example of Induction in magentism • Transformer The needle of a compass point to the north pole because it is the __________ side of the magnet • South This occurs when the Earth’s magentic field ejects charges particles. • Aurora
