  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...
