How to find force from magnetic field?

[Bilbo B]

Given a circular loop with current flowing placed in an external magnetic field. How to account for the magnetic force the field is going to exert on the loop and in what ways it will affect it? Will it will produce any motion if the magnetic field is constant and no change in flux?
