Magnetism: 12.5 kiloGauss = lbs pull

  1. Feb 26, 2007 #1
    12.5 kiloGauss = how many lbs pull .
    I want buy a bunch of 3/8" x 1/4" NEODYMIUM magnets.
    Some sellers designate Gauss, other lbs pull.
    Also, any tips on where to buy?

    Gauss is a measure of magnetic flux density. Pounds are a unit of force. There is no simple conversion because they are not measurements of the same thing. In order to compare them, you would need to know more information about how and the measurements were taken.

    "Lbs pull" is proportional to the end area of the magnet times the B field in gauss, so they are not equivalent units. Which you use depends on what you want to use the magnet for.
