magnetostatic field

A magnetostatic field is a stationary magnetic field that remains constant in magnitude and direction at any given point. These fields are found around permanent magnets or in the vicinity of a steady electric current flowing in one direction.1

Magnetic fields are a fundamental concept in physics, representing a vector field where magnetic forces are observable. They are generated by magnets, electric currents, or changing electric fields. Magnetic fields exert forces on moving charged particles, causing them to move in circular or helical paths. This interaction is the basis for electric motors.1

Magnetic fields can be visualized using lines of force, also known as magnetic flux lines, which emerge from north poles and enter south poles. The density of these lines indicates the field's strength. Mathematically, magnetic fields are described by vectors, with two key quantities: magnetic flux density (B) and magnetic field strength (H). Maxwell's equations provide a comprehensive description of electric and magnetic fields and their interactions.12
