Numerous Application: Fishing , Searching iron.

Quantity: 1Piece Magnet per package

Note:

1.The magnetic pull-force 250KG was tested using a computer-controlled tensile tester, it is the vertical pull-force which make the fishing magnet pull away from a 30mm thicknesssteel plate under ideal condition. The actual pull-force will varymainly depending on the following factors:

A:Steel thickness:The thinner the steel , the lower the pull-force,250KG vertical pull-forcewas 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 addtion, 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 hardlyany 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.
