PPT-Magnetism and Electromagnetism

Magnetism day 1 What causes magnetism How is magnetism linked to electric charges Magnetic fields come from moving charges a moving charge around an atom produces a magnetic field currents in wires will produce magnetic fields. Knowing about the properties of electromagnets is a crucial underpinning for understanding how magnetic 57374elds are generated in nature in the surface of the Sun and in the interior of Earth In preparation for this activity or as a followup please A unit of measure of . magnetic field strength. , the _____________, is named after him.. connected. oersted.
