–The magnetic pull force 150KG was tested using a computer-controlled tensile tester, it is the vertical pull-force which make the fishing magnet pull way from the steel plate 10mm thickness under ideal condition. The actual pull force will vary mainly depending on the following variables:
a: Steel thickness :The thinner the steel, the lower the pull force, 150KG vertical magnetic pull force was got on base of 10mm thickness steel Plate
b: Pulling direction :The bigger of the pulling direction beyond 90°, the lower the pull force, normally the Pull force in horizontal direction is only about one third of that in vertical direction.
c: Attracting position :The farther beyond the center of gravity, the lower the pull force.
In addition, iron chips of magnetic surface also reduce the pull-force of magnet at some extent.
–Magnet just only attract iron , ferrous metal and nickel, do not attract gold, silver, copper, aluminums and their alloy and stainless Steel
–Magnetic force concentrates on the bottom of the fishing magnet, there is hardly any magnetic force of other surfaces .
