Hello,

What's the difference?
Being in a uniform or nonuniform magnetic field?
If a magnetic moment(magnet) is place in both, what is the result?

And, is an electromagnet's magnetic field uniform or nonuniform?
I do know that a Solenoid is uniform, but not sure about an electromagnet though.

A magnetic moment will experience a torque in any magnetic field.
It will only experience a force in an inhomogeneous magnetic field.

The magnetic field outside an electromagnet or a finite length solenoid is nonuniform.
It is the field of a magnetic dipole, which is given in most textbooks.
