This page lists examples of magnetic induction B in teslas and gauss produced by various sources, grouped by orders of magnitude. Note: * Traditionally, magnetizing field H, is measured in amperes per meter. * Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m2]. * One tesla is equal to 104 gauss. * Magnetic field drops off as the cube of the distance from a dipole source.
