electric current that flows in only one direction

a device that converts electrical energy into mechanical energy by using the magnetic forces between an electromagnet and a permanent magnet to make a shaft rotate

temporary magnet created when there is a current in the wire coil

the attractive or repulsive force between electric charges and magnets

process by which electric current is produced in a wire loop by a changing magnetic field

interaction between electric charges and magnets

device that uses an electromagnet to measure electric current

device that uses electromagnetic induction to convert mechanical energy into electrical energy

group of atoms in a magnetic material in which the magnetic poles of the atoms are aligned in the same direction

region surrounding a magnet that exerts a force on other magnets and objects made of magnetic materials

region on a magnet where the magnetic force exerted by a magnet is strongest

the properties and interactions of magnets

a cylindrical coil of wire, used to produce a magnetic field when an electrical current passes through the wire

device that uses electromagnetic induction to increase or decrease the voltage of an alternating current

large wheel that rotates when pushed by steam, wind, or water and provides mechanical energy to a generator
