>drifts around its original position instead of one way to the lower field
We have an old wide bore 400 that drifted up for ~3 months after charging.
I *think* the coil was cooling and contracting which created more teslas.
Does the oscillation follow the barometer? Many magnets seem to have
difficult births, but still end up being wonderful pets :).
