Material:Neodymium Magnet+A3 steel+Black Resin
Net Weight of magnet : 0.5KG
Working Tempearture: Under 80 degree centigrade
Note:
1.The magnetic pull-force400LBS was tested using a computer-controlled tensile tester, it is the vertical pull-force which make the fishing magnet pull away from a 30mm thickness steel plate under ideal condition. The actual pull-force will vary mainly depending on the following factors:
A: Steel thickness: The thinner the steel , the lower the pull-force, The thinner the steel , the lower the pull-force, 400LBS vertical pull-force400LBS vertical pull-force was get on base of 30mmthickness 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 is ;
In addition, iron chipsof magnetic surface also reduce the pull-force of magnet at some extent
2.Magnet just only attract iron , ferrous metal and nickel, do not attract gold, silver, copper, aluminiums and their alloy and stainless steel;
3.Magnetic force concentrates on the bottom of the fishing magnet, there is hardly any magnetic force of other surfaces
Warnings:
Strong Magnet could pinch your finger badly;
Keep strong magnet away from Children;
Do not allow magnets to attach together (especially naked neodymium magnet), any cracks and chips could hurt your eyes.
