Problems:
A rectangular loop of wire with sides H = 38 cm and W = 57 cm carries current I2 = 0.361 A. An infinite straight wire, located a distance L = 27 cm from segment ad of the loop as shown, carries current I1 = 0.735 A in the positive y-direction.
1) What is Fad,x, the x-component of the force exerted by the infinite wire on segment ad of the loop?
2) What is Fbc,x, the x-component of the force exerted by the infinite wire on segment bc of the loop?.
3) What is Fnet,y, the y-component of the net force exerted by the infinite wire on the loop?
4) Another infinite straight wire, aligned with the y-axis is now added at a distance 2L = 54 cm from segment bc of the loop as shown. A current, I3, flows in this wire. The loop now experiences a net force of zero.
What is the direction of I3?
- along the positive y-direction
- along the negative y-direction
5) What is the magnitude of I3?
Three infinite straight wires are fixed in place and aligned parallel to the z-axis as shown. The wire at (x,y) = (-15.5 cm, 0) carries current I1 = 2.6 A in the negative z-direction. The wire at (x,y) = (15.5 cm, 0) carries current I2 = 1.3 A in the positive z-direction. The wire at (x,y) = (0, 26.8 cm) carries current I3 = 6 A in the positive z-direction.
1) What is Bx(0,0), the x-component of the magnetic field produced by these three wires at the origin?
2) What is By(0,0), the y-component of the magnetic field produced by these three wires at the origin?
3) What is Fx(1), the x-component of the force exerted on a one meter length of the wire carrying current I1?
4) What is Fy(1), the y-component of the force exerted on a one meter length of the wire carrying current I1?
5) What is Fx(2), the x-component of the force exerted on a one meter length of the wire carrying current I2?
