3 Magnetism (Right) W. is a magnet? What is a magnetic field?
How is a magnetic field made? Magnet: an object or material that has a magnetic field 2) Magnetic field: an area where an object is affected by a magnet 3) A magnetic field is made by moving electrical charges (electric currents). Electric charges can be attract or repel like magnets.
