Coil inductor make? Answered

I have, what I believe is, a neodymium ring magnet (pictured) that measures approximately 1.6 cm across x 0.3 cm thick and it has an inner diameter of of about 1 cm. I have been debating on what to do with it (also open to suggestions) hence the title. My question is how do I attempt to predict the performance of a coil created with this?

Any engineer would wind just a few turns and measure the magnetizing curve to make predictions of a larger winding.
