Thanks MarkT,

my background is in ecotoxicology and biology (some school physics), so I think I'll have even more physics questions when these magnets arrive!

How can I readily measure torque in my home office?  I have a hobby PSU which will measure supplied volts and current draw and hobby multimeter.

One website says I should measure motor torque rating at point when the motor is stalled, when lifting a mass. If I measure current drawn at this point, with and without the magnets, does this give me a fair comparison?

Cheers

Should do - due to static friction I'd measure the current to start lifting the mass and the current at which it stalls again, take the average.
