Quadrupole magnets are useful as they create a magnetic field whose magnitude grows rapidly with the radial distance from its longitudinal axis. This is used in particle beam focusing. The simplest magnetic quadrupole is two identical bar magnets parallel to each other such that the north pole of one is next to the south of the other and vice ...
The magnetic pole model assumes that the magnetic forces between magnets are due to magnetic charges near the poles. This model works even close to the magnet when the magnetic field becomes more complicated, and more dependent on the detailed shape and magnetization of the magnet than just the magnetic dipole contribution.
A magnetic gear is composed of magnets of the type permanent, electromagnetic or otherwise magnetically induced fields. It consists of two or more elements that are usually rotating but can be linear or curve linear in nature. The classical gear is defined as a ratio of pole pairs. Where the Pole pairs are magnets N-S and S-N in nature.
Magnetic field of a simple bar magnet. A dipole magnet is the simplest type of magnet. It has two poles, one north and one south. Its magnetic field lines form simple closed loops which emerge from the north pole, re-enter at the south pole, then pass through the body of the magnet. The simplest example of a dipole magnet is a bar magnet. [1]
For an electromagnet with a cylindrical bore, producing a pure multipole field of order , the stored magnetic energy is: =!. Here, is the permeability of free space, is the effective length of the magnet (the length of the magnet, including the fringing fields), is the number of turns in one of the coils (such that the entire device has turns), and is the current flowing in the coils.
