The Science of Magnetic Field Lines - ThoughtCo

  • Using magnetic field lines to construct a map, some rules become apparent: 1. Magnetic field lines never cross. 2. Magnetic field lines are continuous. They form closed loops that continue all the way through a magnetic material. 3. Magnetic field lines bunch together where the magnetic field is strongest. In other words, the density of field lines...
