shooting in another example a neodymium magnet of type n38 n40 n42 n45 n48 n50 or n52 manufactured by k amp j magnetics inc www kjmagnetics com of 2110 ashton dr jamison pa 18929 may be suitable exemplary properties of neodymium magnets manufactured by k amp j magnetics inc are presented in table 2 below a brmax residual induction also called u201c residual flux density u201d it is the magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed this is the point at which the hysteresis loop crosses the b axis at zero magnetizing force and represents the maximum flux output from the given magnet material measured in gauss in the cgs system and presented above in kilo gauss kgs b bhmax maximum energy product the magnetic field strength at the point of maximum energy product of a magnetic material the field strength of fully saturated magnetic material measured in mega gauss oersteds mgoe referring to fig6 and 7 a the magnet 78 may be shaped to key into an opening 82 in the wall 84 that connects between the opposing parallel walls 66 of the mount 10 below the deck adhesive such as loctite u00ae 411 may be applied to a bench 86 or adjacent the opening sidewall 88 to secure the magnet within the opening alternatively as shown in fig7 b the magnet 78.
