Orders of magnitude (magnetic field)
Comparison of a wide range of magnetic fields / From Wikipedia, the free encyclopedia
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].[1]
- 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.[2]
