Can you move a compass’ needle with a magnet?
And could you move it with a powerful magnet beneath a table?

Yes you could! A decent compass has a very low-friction bearing so it doesn't take much of a magnetic field to turn it (in fact the earth's magnetic field is relatively pretty weak). A fairly powerful magnet can affect a compass from as far as several feet away!

Yes. Sorry for the short answer.

For sure ..and quite easily , as long as compass bearings have very low friction

Yes and yes.
The compass moves in the direction of any magnetic field.

Try it and find out.

Easily. The earth's magnetic field is half a gauss. A small bar magnet can generate 200 times that.

Why ask when you can DO yourself.
This is such an easy test. EXPERIMENT is the key to all science.
Not only can a magnet do this, so can ordinary iron or even iron ore.
"Magnetic Island" was named because it deviated Captain Cook's compass.
I had a bad break in my arm when I was 11 years old. A metal pin was put in.
And then on a compass march with the scouts I noticed that I was off line. I was puzzled until I moved the compass to my LEFT arm. Further from the pin.

In fact, this is how I compare magnets, one to another, easily. If magnet "A" starts deflecting a compass needle at a greater distance than magnet "B", then I know that magnet "A" is the more powerful of the two.
