What size is the cylindrical hole in the center of the cube?

1/2". The device comes with a magnet to to fit into the hole. A 1/2" by 3" cow magnet work fine as well.

What is the maximum size magnet that will fit in the tube?

Ours came with a three (3") inch cow magnet. I bought extras in case one gets lost as they do. The device works great with students demonstrating magnetic fields in 3D. Hope this is useful. Richard

What is the ID of the tube?

A three inch long 1/2" dia cow magnet fits perfectly. It also comes with its own cow magnet. 0.5'is the ID of this device.
