I didn't check, I stumbled across if by accident. One of the frig magnets that was holding a notice got placed on the counter and I found it difficult to pick up.
The magnet does actually stick to the vertical lip of the counter top while holding the notice in place.

Some might have magnetic minerals, but I wouldn’t take that for granted! LOL!

If it's the narrow part in front of the sink, some fabricators recess a piece of rebar in a slot for added strength.

I've noticed this on some tops, especially if there's red/brown in them.

This is my window sill and I know here is no rebar in that piece, that is straight granite.

That means your magnet is magnetic,not the granite. The granite probably has high concentrations of iron.

Yup. Put a magnetic mount flashlight on it, and thought the countertop was "sticky".

Aluminum exhibits magnetic properties..magnetic will "slide" down an angled sheet, rather than fall off. Some of the new super magnetics stick strongly to some granite.

It's probably not only ferrous (magnetic) but also possibly radioactive & emitting radon gas.https://www.epa.gov/radiation/granit...-and-radiation

fify. Copper is similar, but it's diamagnetic.

Umm... I doubt it's magnetic. Magnets stick to my refrigerator door, but the door isn't magnetic.

You might want to keep that granite magnet and have it studied. You are sitting on the next MM$ discovery.

Don't tell Mrs. Garett or she'll have the countertop covered w/pics, notes, etc. once she runs out of room on the fridge.

You thought a granite countertop would be attractive. Little did you know...
