Tungsten aka Wolfram is paramagnetic so it is weakly attracted to magnets.

A guy devised the following to test for Tungsten in gold bars:

But he is using a paperclip and not real Tungsten.

Question: How strong a magnet do I need in order to achieve a significant attraction to Tungsten. By significant I mean that it should exert a force of several (1/100)*grams so that it can be measured with a scale as in the YouTube video.
Will a Neodymium magnet do? If yes, what should be the strength of the magnet in kg?
