Gauss Guns Launch Steel Balls with Magnets! How is a Gauss Gun made? What is needed to make one of your own? How and why does it work? In this article, we study Gauss Guns and analyze some details of their construction. What is a Gauss Gun? The core of a gauss gun consists of a single neodymium magnet with several steel balls stuck to it.

the magnetic particles, consists of an arrangement of multiple separation discs. The magnetic field magnetizes the particles and the separation discs, which causes the two components to attract (step 2). By applying a magnetic field to the magnetic particles, it is possible to extract both the magnetic particles and the adsorbed proteins.

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets ...
