Orders of magnitude (magnetic field)

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 inverse cube of the distance $(1⁄distance3)$ from a dipole source.
 * Energy required to produce laboratory magnetic fields increases with the square of magnetic field.
