The magnetic force is a fundamental force that acts between magnets and magnetic materials. It is responsible for the attraction or repulsion between these objects and plays a crucial role in various natural and technological phenomena.

Magnetic Fields

Magnetic fields are regions around a magnet or a current-carrying conductor where the magnetic force is exerted. These fields are represented by lines of force and have both magnitude and direction. The direction of the magnetic field lines is from the north pole to the south pole outside the magnet and from the south pole to the north pole inside the magnet.

Magnetic Force on Moving Charges

When a charged particle moves through a magnetic field, it experiences a force perpendicular to both its velocity and the magnetic field direction. This phenomenon is known as the Lorentz force and is responsible for the behavior of charged particles in magnetic fields, such as the deflection of charged particles in a cathode ray tube or the operation of a cyclotron.
