Line of force Wikipedia

A line of force in Faraday's extended sense is synonymous with Maxwell's line of induction. According to J.J. Thomson, Faraday usually discusses lines of force as chains of polarized particles in a dielectric, yet sometimes Faraday discusses them as having an existence all their own as in stretching across a vacuum. In addition to lines of force, J.J. Thomson—similar to Maxwell—also calls them tubes of

Electric Field vs Magnetic Field Difference and

It is produced by moving electric charges. The presence and strength of a magnetic field is denoted by "magnetic flux lines". The direction of the magnetic field is also indicated by these lines. The closer the lines, the stronger the magnetic field and vice versa. When iron particles are placed over a magnet, the flux lines can be clearly seen.

Introduction to Magnetism and Induced Currents

Even the magnetic field produced by a current-carrying wire must form complete loops. Above, you were told that a loop of current-carrying wire produces a magnetic field along the axis of the wire. The right-hand rule gives the direction of the field inside the loop of wire. The magnetic field turns back the other way outside of the loop.
