Video: Copper’s Surprising Reaction to Strong Magnets

This video is fascinating to me, the best strange thing for today. It shows magnetic breaking using a large copper plate and a strong neodymium magnet.

The slowing of momentum looks almost supernatural, like something in the Matrix.

The large copper plate is not magnetic, but it slows a strong magnet’s movement due to rapidly induced electron movement in the plate which creates temporary electromagnetic forces to oppose the approaching magnet. There is no attraction or repulsion in this interaction, just resistance to change.

Can you think of practical uses for this effect?

Brakes on trains and roller coasters might be one application.

It does look unnatural. Nice find.


Hey! I cannot watch the video for some reason! There’s some error apparently, so could you give me the link or check it out please?
