A circular loop of radius R carries a current I₁. A straight wire with a current I₂ in the plane of the loop passes a distance d from the loop center.

(a) Use an energy method to show that the force on the loop is

d 1 [OL-R-1] 2. F = poli1 Molly

(b) Interpret your force formula in the limit d >> R in the language of magnetic moments.

d 1 [OL-R-1] 2. F = poli1 Molly
