Would it work? Probably.
A magnetic pickup is legitimately just wire wrapped around a magnet. The devil is in the details in terms of getting it to work well. If I recall you'd want more or less 42 AWG lacquer-insulated wire to get a good impedance within a number of winds, and whether or not the size/grade of neodymium magnet you're using would be ideal is another thing off the top of my head. That says nothing about the potential impact of the number of windings and potentially even patterns.
Don't let me saying this STOP you, just be aware that if you want it to work well on purpose (beyond happy accident) you'd do well to do some homework.
