kilogauss
Magnetic flux densityexact by definition
The kilogauss is one thousand gauss, exactly 0.1 tesla. It is the unit permanent magnet catalogues are written in: residual induction Br for an N42 neodymium grade is about 13.2 kG, for a good ferrite about 4 kG, and a loudspeaker gap field is around 10 kG. The conversion is exact, the gauss being exactly 1e-4 tesla.
Watch out: A grade's Br is the flux density inside the material in a closed magnetic circuit, not what a gaussmeter reads at the pole face of a magnet sitting in air. Surface field on a small magnet is typically a third to a half of Br, and it falls off steeply with distance.
