What does a magnetic field affect?

A magnetic field affects the magnetic forces surrounding a magnet. This is because magnetic fields are produced by magnets and electric currents, and they exert forces on other magnets, magnetic materials, and electric currents passing through conductors within the field. When we refer to the magnetic forces around a magnet, it relates to the ability of the magnetic field to attract or repel other magnetic objects, which is a fundamental characteristic of magnetism.

The interaction described is critical in many applications, such as in motors, generators, and magnetic storage devices, where the effect of the magnetic field on materials and currents plays a significant role in their operation. Understanding the influence of magnetic fields helps to explain a wide range of physical phenomena and technological applications related to electromagnetism.
