... solenoids can produce more force than their equivalent size continuous-use counterparts. Increasing the amount of Amperes by lowering the coil wire resistance also reduces the number of turns on the coil, for a given physical diameter, because the size of the wire (wire diameter) must also increase, ...

... There are two types of poles – N pole and S pole. Each magnet has (at least) one N pole and one S pole – it is impossible for a magnet to have only one pole. The two poles are near the ends but inside the magnet. The magnetic interaction is very weak (or zero) at the midpoint between the two poles. ...

Magnetochemistry
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic. The magnitude of the paramagnetism is expressed as an effective magnetic moment, μeff. For first-row transition metals the magnitude of μeff is, to a first approximation, a simple function of the number of unpaired electrons, the spin-only formula. In general, spin-orbit coupling causes μeff to deviate from the spin-only formula. For the heavier transition metals, lanthanides and actinides, spin-orbit coupling cannot be ignored. Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.
