Types of magnets

thumb|upright=1.5|A magnetite rock is being pulled by a [[neodymium magnet on top.]]

thumb|A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. The strength of the magnetic field generated is proportional to the amount of current through the winding.

type of magnet

type of particle accelerator

electromagnet made from coils of superconducting wire

magnet, which is used to post items

permanent magnets made from alloys of rare earth elements

lens for charged particles

special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side

consist of groups of four magnets laid out so that in the planar multipole expansion of the field, the dipole terms cancel and where the lowest significant terms in the field equations are quadrupole

magnet in which opposite poles are on opposite sides of the magnet

magnet with the shape of a horseshoe

bistable permanent magnet

consist of six magnetic poles set out in an arrangement of alternating north and south poles arranged around an axis
