If a magnet is broken in two, it merely forms two new north and south poles in the middle, so that one end never exists without the other. However, some modern theories suggest that magnetic monopoles may exist, and so the magnetic monopole term is sometimes included in the equations. Current theories suggest that, just as electricity and magnetism may be unified as the electromagnetic interaction, so may the weak force and the electromagnetic force, as the electroweak interaction. The weak interaction has the Z and W bosons as its field carriers. At very high energies, such as those produced in particle accelerators, the photon and the Z boson look very similar.
Electromagnetic phenomena pervade our lives.
All electrical apparatus, static electricity, magnets, motors, dynamos and natural phenomena such as lightning may be understood by the use of Maxwell's equations.
