Magnetism: Physics Of

: Unlike electric field lines, magnetic field lines always form continuous, closed loops; they do not have a starting or ending point.

: The lines are closest together at the poles, indicating that the magnetic force is strongest in those regions. Physics of Magnetism

: Magnetic field lines never cross each other at any point. Licensed by Google : Unlike electric field lines, magnetic field lines

: By convention, magnetic field lines exit from the North Pole and enter through the South Pole . : Unlike electric field lines

A fundamental feature of magnetism is the , which describes the invisible area of influence surrounding a magnet where magnetic forces can be detected. Key Characteristics of Magnetic Fields
