Magnetic field pattern. Clumping of iron filings in the presence of a magnetic field from a ring magnet. The magnetised iron filings align due to the interactions between them,even though the magnetic field itself is continuous. Magnetism is a property of ferromagnetic metals (such as iron,nickel and cobalt) caused by the alignment of the spins of the electrons in the metal | |
