The net force on a current loop in a uniform magnetic field is zero. But what if B is not uniform? The figure (Figure 1) shows a square loop of wire that lies in the zy-plane. The loop has comers at (0,0), (0, L), (L,0), and (L, L) and carries a constant current I in the clockwise direction. The magnetic field has no ar-component but has both y- and z- components. B= (Boz/L) 3+ (Boy/L) k, where Bo is a positive constant

Transcribed Image Text:The net force on a current loop in a uniform magnetic field is
zero. But what if B is not uniform? The figure (Figure 1)
shows a square loop of wire that lies in the zy-plane. The
loop has comers at (0,0), (0, L), (L, 0), and (L, L) and
carries a constant current I in the clockwise direction. The
magnetic field has no z-component but has both y- and z
components: B = (Boz/L)+(Boy/L) k, where Bo is
a positive constant.
