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 $(.mw-parser-output .sfrac{white-space:nowrap}.mw-parser-output .sfrac.tion,.mw-parser-output .sfrac .tion{display:inline-block;vertical-align:-0.5em;font-size:85%;text-align:center}.mw-parser-output .sfrac .num{display:block;line-height:1em;margin:0.0em 0.1em;border-bottom:1px solid}.mw-parser-output .sfrac .den{display:block;line-height:1em;margin:0.1em 0.1em}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}1/distance3)$ from a dipole source.
Energy required to produce laboratory magnetic fields increases with the square of magnetic field.
