A current-carrying circular loop of wire (radius r, current I) is partially immersed in a magnetic field of constant magnitude B0 directed out of the page as shown in the figure.(Figure 1) Part A Determine the x, y, and z projections of the net force on the loop due to the field in terms of θ0. (Note that θ0 points to the dashed line, above which B = 0.)
A flat circular loop of wire of radius R carrying a current I is placed in a uniform magnetic field B that is directed in the plane of the current loop. What is the magnetic moment M of the loop?

4. Consider a circular loop of wire with a mass m and a radius R. The circular loop is vertical such that gravitational force on the loop points straight down. You may assume this is near the surface of the earth such that the force of gravity has a magnitude FGl mg. The upper half of the circular wire is immersed in a uniform magnetic field B pointing into the page. In the figure below this corresponds to the region...
