Magnetic Domains (cont.) Opposing electron spins: magnetic field cancels Similar spins magnetic fields add together called domains large group of similarly spinning electrons create a strong magnetic field. North pole spins one way, south pole the other way. Domains can be permanent or temporary. a...
