25mm O.D. x 16mm I.D. x 5mm thick Unmagnetised Neodymium Ring ( Pack of 1 )
25mm O.D. x 16mm I.D. x 5mm thick Unmagnetised Neodymium Ring ( Pack of 1 )

Non-magnetic Neodymium (N42) ring.

  • 25mm outer diameter x 16mm inner diameter x 5mm thick
  • Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish

These Neodymium rings are identical in size and shape to our F2516 ring magnets. They can be used with the F2516 ring magnets to demonstrate how the intriguing 'eddy currents' produced by a magnet and copper pipe create a damping effect. A non-magnetic ring will slide down a length of copper pipe in an instant but the magnetised variation will descend slowly. A great way to bring magnets to life in the classroom.
