How Are Neodymium Magnets Listed on Your Site?
Every listing shows size, grade, pull force, coating, magnetization direction and volume pricing in the same order.
How Is the Surface Field Measured?
A gaussmeter probe measures the field at the magnet's surface in gauss or tesla. It's a different measure from pull force.
How Are Neodymium Magnets Made?
The NdFeB alloy is melted, milled to fine powder, pressed in a magnetic field, sintered, machined, plated, magnetized and inspected.
Are Neodymium Magnets the Same as Rare Earth Magnets?
Neodymium magnets are one kind of rare earth magnet. The other main kind is samarium cobalt.
What does pull force mean?
Pull force, also known as magnetic pull, is a measure of the strength of a magnet's magnetic field. It is the force that a magnet can exert on an object made of ferromagnetic material, such as iron, nickel, or cobalt. The pull force of a magnet is determined by the strength of its magnetic field and the size and shape of the magnet. Often measured in pounds or kilograms, the pull force is the force required to pull that magnet straight free from a thick steel plate. The pull force also tells you the limit of that magnet's holding power.Generally,...
