basic magnetism
what are magnets
Anything that attracts iron and materials that contain iron
what is an insulator
material that slows down or steps electric current or heat from flowing
what is an electrical motor
a device that changes electrical energy into mechanical energy
what is magnetism
the attraction or repulsion of magnetic materials
what is a conductor
material that allows electric current or heat energy to flow through easily
what happens to magnetic poles that are alike
they repel each other
what is an electromagnet
a type of magnet in which the magnetic field is produced by an electric current
what happens to poles that are unlike
they attract
what is an induction
when movement is used to create electricity
what is a magnetic field
the area of magnetic force around a magnet
what are generators
electric generators convert mechanical energy into electrical energy using induction
