Product Description

Neodymium Fishing Magnet /Salvage Magnet

It is mainly made up of a high grade neodymium magnet and a steel shell, the steel shell is crucial to amplification of magnetic force, it can concentrate the powerful magnetic field on the bottom of magnet which increase the magnetic force by 2.5-4 times compared to the naked magnet. At the same time, the steel cup can prevent the naked magnet from scratch and chipping during grabbing and clamping.

Xhigh retrieving magnets are designed for heavy duty and underwater use. It can help to recover lost equipments, tools, fishing tackles and other ferrous objects in deep water, wells, holes. It is also great for magnet fishing, lifting, hanging and retrieving applications.

Note:

1.The magnetic pull force was tested using a computer-controlled tensile tester.The actual pull force will vary mainly depending on the following variables:
 

a: Steel thickness: The thinner the steel, the lower the pull force,   Magnet just only attract iron, ferrous metal and nickel, do not attract gold, silver, copper, Ali and their alloy and stainless stee.Magnetic force concentrates on the bottom and another side of the fishing magnet,there is hardly any magnetic force of other surface.

 
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.
 
2.Magnet just only attract iron, ferrous metal and nickel, do not attract gold, silver, copper, aluminums 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 .
