Sometimes customers get a bit confused as to how 6x2mm magnet is more surface gauss
than the 25x5 and that the 25x5 is same as the 15x3?
Above magnet size here is only for example, based on same magnet property or Grade N38,
let's explain this technical data from physical characteristics point of view,
the neodymium magnet surface gauss can be figured out as following:
Length to diameter ratio* Br(remanent magnetism), for example N38, Br: aound 12000-12800gauss,
D25x5 reference surface gauss is about 5/25*12000 = 2400
However, actual surface gauss will be a little lower than 2400,
around 2300gauss tested by Gaussmeter, magnetic flux meter, magnetometer, Tesla meter and CTS Gauss meter.
