Study Guide Electromagnetic Review Magnetic and Define Electric circuit - a continuous flow of electrical charges caused by the motion of electrons, expressed in amps Magnetic field - the area around a magnet in which magnetic forces act Magnetic force - the repelling or attraction of a magnetic Static electricity an object - the buildup of electric charges on Electrical conduction – a method of charging an object when electrons move from one object to another by touch Electrical induction – a method of charging an object that occurs when charges in an uncharged object are rearranged without direct contact from a charged object. Permanent magnet – are made from materials hard to magnetize to keep their magnetic properties better. Temporary magnet – are made from materials that are easy to magnetize but tend to lose their magnetic properties Generator – a device that uses electromagnetic induction to convert kinetic energy into electrical energy Electric force – the push or pull from the repelling or attraction of opposite charges Electromagnet - a magnet that consists of a solenoid wrapped around an iron core. 1. What is the Law of Electrical Charges? Like charges repel and opposite charges attract 2. How does this relate to magnetism? Like poles repel and opposite poles attract 3. Draw two magnets that experience a repulsive force. 4. Draw two magnets that experience an attractive force. 5. Draw a bar magnet with its magnetic field. 6. Where are magnets the strongest? At the poles 7. How can you increase the power of an electromagnet? Add a stronger battery, add more loops around the iron core or have a bigger iron core. 8. Draw a magnet and surrounded by compasses. Make sure you label the compasses correctly based on their location to the magnet. 9. Draw the Earth. Draw a compass next to it and label the north and south pole of the compass. Which way does the compass point?
