Magnetic moment in a uniform/non-uniform magnetic field?

  1. May 16, 2013 #1
    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.
