  • Permanent Magnets HyperPhysics ConceptsMagnet Wikipedia

    A good permanent magnet should produce a high magnetic field with a low mass and should be stable against the influences which would demagnetize it The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materialsA magnet is a material or object that produces a magnetic field This magnetic field is invisible but is responsible for the most notable property of a magnet a force that pulls on other ferromagnetic materials such as iron and attracts or repels other magnets
