No, no magic is involved, and as such, magnets are not suitable for use in applications requiring small amounts of energy. The most commonly seen application for magnetic fields in power generation is the generation and transmission of electricity from generating sources of power. Some electrical applications are based around magnetic power transmission, such as transmission of high-voltage power over long distances over magnetic (magnetic) lines of sight (see magnetic transmission), or the generation of alternating current to power the electrical power generators of large buildings. Magnetic fields are applied across a wide band of electromagnetic waves, and they are useful for the transmission of power over a wide range, including through the ocean, a wide variety of medium-range objects (such as aircraft and trains, and vehicles of all sizes), and through a wide range of liquids. The field strength is also useful for the propagation of signals and the propagation of the magnetic fields.
There is no practical use for magnetism in generating electric power in a power plant; however, it may also be used for transmission by use of generators and power line. It can be used in industrial (including mining) applications for power generation, and in remote area areas for power transmission. The practical usage is mostly for large-scale generators in power plants, as they are much more efficient and require far less land and water resources.
For example, in Russia, a large-scale generation of 2GW has been achieved from 4km3 of magnetized water . A similar situation is found in some areas of the US Midwest, where there is an extensive system of generating facilities [6,7]. These generators use magnetism to produce large amounts of electricity via small-scale generators and can operate for many years without any maintenance of the magnetism (provided the magnets are installed on power lines or in appropriate buildings). The efficiency of this magnetism is as high as 100%.
It is also possible that large-scale generators using magnetism to generate electricity can generate large quantities of power. The feasibility of such applications is unclear at present, as such generators would generally require a large-scale network (see below), and they would also require many moving parts, which could require a very large number of them. However, there is reason to believe that this is a realistic possibility, for a number of reasons.
