microtesla
Tiny flux unit
A microtesla is one millionth of a tesla, the unit measuring magnetic field strength.
Microteslas are the typical scale for everyday magnetic fields—Earth's magnetic field measures around 25 to 65 microteslas, and exposure limits for electronics and health studies are often expressed in microteslas.
