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

Click For Summary
SUMMARY

The discussion clarifies the differences between uniform and non-uniform magnetic fields, specifically regarding the behavior of magnetic moments. A magnetic moment experiences torque in both types of fields but only experiences force in a non-uniform magnetic field. It is established that while a solenoid generates a uniform magnetic field, the magnetic field produced by an electromagnet is non-uniform outside of its core. This distinction is critical for understanding magnetic interactions in various applications.

PREREQUISITES
  • Understanding of magnetic moments and torque

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?
 
Physics news on Phys.org
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.
 
Thanks.
