Can a magnet affect a beam scale?

[chuck nelson]

I’m wanting to put a magnet bar in close proximity to my scale. Scales rely on magnetic force to dampen, but nothing on the bar is actually attracted to the magnet. Because of this I assume there shouldn’t be a problem. Am I wrong in thinking this?

Depends how strong and how close. Are to trying to get better damping effect?

magnet will dampen the oscilations and get you to a reading much faster... but that energy will also make the beam less sensitive. Enough to matter?

Do the kernel of powder test. If it reacts, then the forces are not a problem... if you can put in a few kernels with nothing moving, then you have dampened too much.

The scales that have magnetic dampening do so through a copper plate which is what kind of material required , I don't know that a magnet will affect it if it isn't copper.

I have a few scales with that feature a 505 and a dillon both have magnets and the copper strip

I didn't know copper was magnetic. I thought you needed iron. Maybe so with some of those rare earth magnets.

Sounds like making a generator - strip of copper, aluminum, whatever conductor passing through a fixed magnetic field will have an electrical current, and a counter EMF (kind of like a resistance to current flow) generated within it. The "generator" stops "generating" when either the conductor stops moving or the magnetic field disappears

 

[Potashminer]

I guess a better explanation, is that the induced current flow (from the motion) also produces a magnetic field, that is in opposition to the original field - hence a "braking" effect - or a dampening effect, in this case...

The metal has to be conductive, but not magnetic by itself.
So Aluminum, copper, silver, gold to name a few.

Drop a magnet through a length of copper plumbing pipe. The stronger the magnet the more pronounced the effect.

Are you talking about magnetic lines of flux and stuff like that?
