I'm trying to find a small motor or solenoid that does not have permanent magnets. I've searched for a while but can't find anything even though I'm sure it exists.
Does anybody know where I could find such things?
The solenoid or motor will be used next to a magnetometer so it can't have any permanent magnets affecting the measurements.
