magnetostatics

Magnetostatics is a branch of physics that studies magnetostatic properties and deals with stationary magnetic fields. These fields are created by steady electric currents or permanent magnets and remain constant in magnitude and direction at any given point. This contrasts with changing magnetic fields, which can induce electric currents.

Gauss's law for magnetism, a fundamental principle in this field, states that the magnetic flux across any closed surface is zero. This implies that isolated magnetic poles, known as monopoles, do not exist. Magnetostatics is a component of the broader study of electromagnetism, which unifies the understanding of electric and magnetic forces.
