Magnetjõud

Magnetjõud is the Estonian term for magnetic force. It is a fundamental force in nature, responsible for the attraction and repulsion between magnetic objects and the interaction between moving electric charges and magnetic fields. This force is mediated by the magnetic field, which is generated by moving electric charges or intrinsic magnetic moments of elementary particles.

Magnetic forces are experienced by magnets, such as the interaction between a permanent magnet and a piece of iron, where the magnet attracts the iron. They also play a crucial role in electromagnetism, where electric currents create magnetic fields and vice versa. This principle is the basis for electric motors, generators, and transformers. The strength and direction of the magnetjõud depend on the strength of the magnetic fields involved and their relative orientation.

The concept of magnetjõud is described by Maxwell's equations, which unify electricity and magnetism into a single framework. In particle physics, the magnetic force is one of the four fundamental forces, alongside gravity, the weak nuclear force, and the strong nuclear force. Understanding magnetjõud is essential for numerous scientific and technological applications, from everyday devices like compasses and credit card readers to advanced technologies in medical imaging and particle accelerators.
