1. ## Magnetic field - Wikipedia

A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is represented by a vector field.

3. ## Field line - Wikipedia

A field line is a locus that is defined by a vector field and a starting location within the field. Field lines are useful for visualizing vector fields, which are otherwise hard to depict. Unlike longitude and latitude lines on a globe, or topographic lines on a topographic map...

6. ## Magnets and Electromagnets

• The lines of magnetic field from a bar magnet form closed lines.
• As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material.
