An arc of a circular loop of radius R is kept in the horizontal plane and a constant magnetic field B is applied in the vertical direction as shown in the figure. If the arc carries current I then find the force on the arc.

Question

An arc of a circular loop of radius R is kept in the horizontal plane and a constant magnetic field B is applied in the vertical direction as shown in the figure. If the arc carries current I then find the force on the arc., I R B, IRB 4, 2 IRB, IRB 2

If this loop is close net force on it will be zero so F + F straight = 0 ⇒ F = - F straight F = I 2 RB F = 2 IRB
