Representing magnetic fields: in theory IOPSpark

magnetic field  The north and south magnetic poles have opposite positive and negative polarities, like a bar magnet The invisible lines of the magnetic field The magnetic field is the area around a magnet that has magnetic force All magnets have north and south poles Opposite poles are attracted to

Magnetism is a force that is intimately related to electricity Whenever an electric current flows there will be an associated magnetic field in Magnetic Field Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with

Any current will create a magnetic field Certain materials are magnetic field is modulated by z
