I simultaneously agree, and say "wait but..." to myself. Think about the classic method of visualizing the orbital magnetic field from a straight conductor and how that field creates flux density changes as the FIELDS intersect (or more accurately, Don't intersect) causing attraction on the...
Since the external field of the solenoid is in opposite direction than the internal concentrated flux, I could see that field interfacing with the uniform external field, but with an opposite B vector. Is that what you mean?
A solenoid, of sufficient length to consider external flux to be zero, passes through a uniform magnetic field with significant length on both ends extending beyond the field.
Will a torque be exerted upon the solenoid ? Or do the windings effectively mask the internal solenoid field from the...
