magnetic field

A magnetic field is an invisible force field surrounding certain materials, like magnets, that can attract or repel other objects. It is created by moving electric charges, such as electrons, within materials or electric currents. The field extends outward from the magnetic object, influencing other magnetic materials and charged particles within its range. Think of it as a magnetic "force zone" that operates invisibly, guiding magnetic materials and affecting how electric currents move in devices like motors and compasses. This field is essential for many technologies and natural phenomena involving magnetism.
