1. It mainly consists of a high-grade neodymium magnet and a steel shell. The steel case is crucial for enhancing the magnetic force, it can concentrate the Powerful magnetic field at the bottom of the magnet,which increases the strength of the magnet to more higher than that of a normal neodymium magnet.At the same time, a steel cup can prevent the exposed magnet from scratching and chipping during gripping and clamping.
2. The magnets are designed for heavy duty and underwater use. It can help restore lost equipment, tools, fishing gear and other black objects in deep water, wells, holes. It is also great for magnetic fishing, lifting, hanging and retrieving applications.
1. Magnetic pull force was tested using a computer tensile tester. Actual traction force will vary mainly depending on the following variables:
A: steel thickness: the thinner the steel, the lower the pulling force.Vertical magnetic pulling force was obtained on the basis of 30mm thickness of the steel plate.
B: direction of extrusion: the greater the direction of extrusion is at 90deg, the lower the extrusion force, usually the extrusion force in the horizontal direction is only about one third of that in the vertical direction.
C: attracting position: the farther from the center of gravity, the lower the pulling force.
2. Magnet only attracts iron, ferrous metal and nickel, does not attract gold, silver, copper, aluminium and their alloy and stainless steel.
3. The magnetic force concentrates on the bottom of the fishing magnet, there is almost no magnetic force on other surfaces.
NdFeB Pot Magnets are best for small sized magnetic products with maximum pull strength (ideally when in direct contact with ferromagnetic e.g. mild steel surfaces). The actual pull force achieved is dependent on the surface that is being clamped onto (material type, thickness, flatness, friction levels, etc), its quality (e.g. rust free), its size (thickness plus total surface area), etc.
As always everything is excellent. I became a regular buyer from this seller. Yes the delivery is a little uncomfortable, but also the price it keeps the lowest at Taobao level. Magnets are very powerful. Had stupidity in coming to give the child as a result of the child in his wife and my fingers injuries. They are unrealistically difficult to unpair only with lomics.
