magnetjõudude

Magnetjõudude refers to the forces exerted by magnetic fields. These forces are responsible for phenomena such as the attraction between magnets and the repulsion between like poles. They arise from the motion of electric charges, such as the electrons orbiting atomic nuclei or flowing in an electric current. A magnetic field is a region of space where a magnetic force can be detected. This field is often visualized using magnetic field lines, which indicate the direction and strength of the force.

The strength of a magnetjõud depends on several factors, including the strength of the magnetic field, the magnitude of the magnetic moment of the object experiencing the force, and the distance between the magnetic sources. Like poles of magnets (north-north or south-south) repel each other, while opposite poles (north-south) attract. This principle is fundamental to the operation of many devices, including compasses, electric motors, and magnetic levitation systems. The study of magnetjõudude is a core component of electromagnetism, a branch of physics that describes the interaction between electric and magnetic fields.
