Copper Coated Neodymium Magnets
« on: March 24, 2023, 01:40:13 AM »
Does anyone know if there exists a specialty outfit that sells
copper coated neodymium magnets?

I'm asking because I may have found an interesting effect.

Two magnets in a static state with a piece of copper between
them acts for all practical purposes the same as placing a
piece of plastic or any other non-magnetic material between
them.  However, if these two magnets are in rapid motion
relative to each other, then something like copper in between
changes the story.  Eddy currents develop in the copper and
the field between the magnets appears to get distorted.  I
have to wonder if this isn't a key component for the development
of a true magnet motor.  I see a similar behavior with plain
nickel plated neodymium magnets but I'm not sure it is as
pronounced as it might be with copper.  I definitely see a
difference with epoxy unplated neodymium magnets.

Not sure yet what it is I hope to find or if there is anything
there that can be exploited.  Just curious if anyone has
bumped into a supplier that has copper plated magnets,
especially if they have them with various thicknesses.

You might look at plating them yourself.

or,
Copper plated items seemingly are popular decor lately. You might find someone near doing small batch for reasonable.

or,
Use copper foil.

Interesting. Good luck.

I do have brush plating copper and other metal solutions
High density ,will keep building thickness with time ..easy Peasy (if it’ll plate ( have some silver in solution “paint”
For base coat if need be .
Even Gold ( if copper is good ? Gold should be “best (er)” ?
Should be a good brush plating application

Great info guys.  Thank you.

I was poking around on the internet and guess what I found?

Cast bullet gas checks.   They may well work for testing purposes.

You might get better results with silver. Diamagnetism is stronger by mass and it's a but denser. Electrical resistance is smaller, which ought to help for something. At the very least, limit heating. Heat dissipation is also superior.
Silver is quite easy to obtain. I happed to be an expert in consumer silver bullion, it used to be my trade.
For experimental purposes, a .999 silver bar, round or coin should suffice. The supply is vast.
Many suppliers now offer .9999 for the same price, medical grade silver. You could brew your own colloidal silver and add a few years of life expectancy ;-)
How to do an actual coating at room temperature, I could not know. Also never tried obtaining true silver foil.

during the homopolar motor experiments there were several devices being tested with counter-rotating disks with magnets in various configurations, and sheet of copper or copper disk between them.


may be worth poking around the homopolar threads

One molecular layer ( graphene)
Off the charts vrs copper etc (1000 fold ??)

 He shows it’s doable using super simple technique
Approx 6:30 mark
  For those unfamiliar with attributes of graphene ,
I would definitely watch beginning….
For those looking to experiment ,
Watch straight through..
Respectfully
Chet K
Ps
As a side note
William Barbat had claims based on  single layer graphene ( harvesting energy from ambient
With various coated coils
However he mentioned ( when we spoke years ago)
Orientation of layer is important for harvesting!
Pps
We also have an open source member that experimented with “plating one layer”
Will touch base and see if any success?

I'll keep my "Carbon Unit" and let the crazies have their AI robots.   :)

So yeah, that might work Chet.  Just a little grey dusting here and
there--we be in business.
