i got it already, thanks

An ordinary bar magnet has a magnetic moment. You place it in an external magnetic field.
Does the bar magnet precess?

I think it does precess...but i don't know why :(
can anyone help? please~~~

There is a reason that the Homework Help Template that you deleted when posting asks for the Relevant Equations. What is the equation that expresses precession based on torque? What is a necessary component of the equation? What is the torque on a bar magnet in an externally applied magnetic field?
