Question

a) Find the magnitude of the force exerted on the top segment of loop by the magnetic field created by the wire. Consider forces pointing toward the right to be positive. Answer in units of Newtons.

b) Find the magnitude and direction of the force exerted on the left segment of loop by the magnetic field created by the wire. Consider forces pointing toward the right to be positive. Answer in units of Newtons.

c) Find the magnitude and direction of the force exerted on the right segment of loop by the magnetic field created by the wire. Consider forces pointing toward the right to be positive. Answer in units of Newtons.

d) Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire. Consider forces pointing toward the right to be positive. Answer in units of Newtons.

Explanation / Answer

F=u0i1i2/2pir

part a)

for top segment, i1 and i2 are perpendicular so F=0

part b)

for left segment

i1 and i2 are in same direction , so force will be attractive

F=4pi*10-7*4.7*13/2pi*0.130=2*4.7*13*10-7/0.13

part c)

for bottom part i1 and i2 are perpendicular so F=0

part d)

for left part i1 and i2 is in opposite direction, so force will eb repulsive

F=4pi*10-7*4.7*13/2pi*(0.130+0.340)=2*4.7*13*10-7/0.470
