Magnetic damping of aluminium vs copper

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. ...

Eddy Currents - K&J Magnetics

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 ...

Copper cables have a current carrying capacity of about 40% higher than aluminum. The larger diameter of aluminum allows it to carry more current per unit length than copper of the same diameter. WebPermeability is the ability to support formation of magnetic fields in a material. Permeability is measured in H/m (henries/m) or newtons/ampere 2 (N/A 2). The Permeability of Free Space.
