I bought a bunch of endmills from a machine shop going out of
business.
The seller told me some of them were carbide.
I saw some of them that were dull grey instead of shiny steel but they
were all magnetic.
Is tungsten carbide magnetic?

Yep, the binder is cobalt which is magnetic.

Tungsten carbide itself isn't, but the cobalt binder is. The endmills also
will be noticeably heavier than HSS.

Ed of course means to say, *denser* than HSS, not necessarily heavier.
