100 What is magnetic poles One of two points, such as the ends of a magnet, that have opposing magnetic qualities	100 What is Danish physicist Hans Christian Oersted Discovered the relationship between electricity and magnetism in 1820	100 What is electromagnetic induction The process of creating a current in a circuit by changing a magnetic field	100 What is any material that attracts iron or materials containing iron Definition of magnet	100 What is the pole of a magnet that points to the north Is called the magnet’s north pole
200 What is magnetic force What happens when you bring two magnets close together?	200 What is electromagnet A coil that has a soft iron core and that acts as a magnet when an electric current is in the coil	200 What is mechanical energy into electrical energy. What energy change happens in an electric generator?	200 What is a coil of wire with an electric current in it Definition of solenoid	200 What is domains But in materials such as iron, nickel, and cobalt, groups of atoms are in tiny areas called
300 What is ferromagnets Magnets made with of iron, nickel, cobalt, or mixtures of those metals.	300 What is they can turn on and off Why are electromagnets very useful?	300 What is the sun, wind, nuclear power plants... What are three sources of energy that are used to generate electrical energy?	300 What is the interaction between electricity and magnetism Definition of electromagnetism	300 What is a magnet made by an electric current. An electromagnet usually has an iron core. A electromagnet is...and usually has...
400 What is a material is magnetic If its domains line up.	400 What is the needle is a small magnet. The needle moves because the electric current in a wire creates a magnetic field that exerts a force on the needle. Why does a current-carrying wire cause a compass needle to move?	400 What is whether it increases or decreases the voltage The number of loops in the primary and secondary coils of a transformer determines	400 What is a device that increases or decreases the voltage of alternating current Definition of transformer	400 What is as more loops per meter are used. How can the strength of the magnetic field of a solenoid be increased?
500 What is near Earth’s magnetic poles because Earth’s magnetic field bends inward at the poles. Auroras are most commonly seen at...because...	500 What is a doorbell, an electric motor, a galvanometer... Devices that make use of electromagnetism	500 What is What is Faraday hoped that the magnetic field of the electromagnet would make—or induce—an electric current in the second wire. What was Faraday trying to do in his experiment?	500 What is a device that converts mechanical energy into electrical energy Definition of electric generator	500 What is making an electric current by changing a magnetic field. Electromagnetic induction is the process of...
