Does Angle Gauge Cause Loading?

I have not experienced the diamond stones becoming magnetized. I have used 5 different brand digital angle devices. The one I’m using now has the strongest magnet. I do see some metal fuzz on the digital cube, sometimes, that I wipe away.

I always zeroed it base down and used it with the magnet attaching it to the stone. I think you’re overthinking it. These are relative angles we’re setting, relative to the zeroed horizontal position. As long as every angle you set using the cube is done with the same method and cube /stone placement relative to the clamped knife, it’ll give you consistent angle measurements.
Also…only zero the cube at the beginning. Do not zero it again while sharpening the knife.

If you have ever magnetized a screw driver to hold a screw you may recall you must drag the magnet from the center of the screw driver to the end with one pole of the magnet. This will align a temporary magnetic field within the steel allowing the screw driver to pick up or old a screw.
Just attaching the magnet gauge to a plate would allow the magnetic field to flow from the south to north pole of the magnets mounted in the gauge. This is what hold that magnet to the steel. You are not dragging the magnet on the stone. So my guess knowing what little I do of magnetism would be no. Using the gauge normally should not leave sufficient magnetism to produce loading of the stone. If you are concerned an inexpensive degaussing can be used to remove any residual magnetism https://www.ebay.com/b/degaussing-coil/bn_7024861917

Is there a better angle gauge out there that can show the correct angle on both stones without you having to flip the face of the gauge away from you or having to do any math?
Ralph your description of your digital device sounds like the Wixey Model Angle Cube. As airscapes says you will get use to it quickly and the math will be second nature. It does work quite well and it’s faster to lock in then many other comparably priced model. I used it for a long time.
To address your quoted question the Floureon DXL360S IMO, is the best, most accurate and lowest resolution unit out there at this time. It does have strong holding magnets on all four sides. It will not cause the steel diamond stones to become magnetized, either. There are similar less expensive models with just slightly lower resolution. I also have used that model and it works well and holds on the stone securely.
Both of these models, DXL 360S and DXL360 have a more detailed initial calibrating procedure that may be confusing to follow in the product manual. I watched a YouTube to help make it more clear. Once initialized and calibrated these both work quite well. I think the more expensive, red, DXL360S is the top pick for precision and accuracy. They are USB rechargeable. They hold a charge a very long time.

I also use the Floureon DXL360S angle gauge and find it to be the best/most accurate of several I’ve used.
I have seen no signs of magnetic loading of the swarf but I really haven’t been looking for it.
The accuracy and USB charging got me to buy it.
