Solenoid | a coil of wire that produces a magnetic field when carrying and electric current |
Generator | device that uses electromagnetic induction to convert kinetic energy into electrical energy |
Magnet | any material that attracts iron or materials containing iron |
Poles | the parts of a magnet where the magnetic effects are strongest |
Electromagnetic induction | process by which an electric current is produced by changing magnetic field |
Electromagnetism | the interaction between electricity and magnetism |
Transformer | increases or decreases the voltage of an alternating current |
Electromagnet | a magnet that consists of a solenoid wraped around an iron core |
Magnetic force | the force between magnets depends on how the poles of the magnets line up (opposites attract) |
