WebMar 14, 2024 · Damping defined by a loss factor behaves somewhat differently from viscous damping. Loss factor damping is proportional to the displacement amplitude, whereas viscous damping is proportional to the velocity. Thus, it is not possible to directly convert one number into the other. WebThis phenomenon is known as Lenz’s Law. The magnetic field induced in the metal attracts the falling magnet, creating resistance. This resistance is what slowed down your magnet. As your magnet slows down, it stops generating as much current, which reduces the resistance acting on the magnet’s movement. Gravity speeds the magnet back up ... diy steady restWebAlthough paramagnetic substances like oxygen, tin, aluminium and copper sulphate are attracted to a magnet the effect is almost as feeble as diamagnetism.

Webdamping mechanisms is retabulated in Table I. Damp- ing mechanisms may also be grouped according to their source; such groups include defect damping, thermoelastic damping, magnetic damping and vis- cous damping (due to micro- or macro-plasticity).

How it works: As the disc spins, electrical currents are induced in the aluminum as it moves with respect to the magnet.

WebMagnetic damping (eddy current damping) is generated when there is a relative movement between magnets and a conducting material (normally Aluminum or Copper). When either a magnet move relative to a conductor or a conductor passes thru a magnetic field, the electromotive force (emf) will be generated inside the conductive material. ...
