Magnetic Force on a Bent Wire Conceptual Question

Part A = +y
Part B = 0
Part C = +x
Part D = -y
Part E = 0
Part F = -y
Part G = -x

Solutions Below:

The bent wire circuit shown in the figure is in a region of space with a uniform magnetic field in the +z direction. Current flows through the circuit in the direction indicated. Note that segments 2 and 5 are oriented parallel to the z axis;the other pieces are parallel to either the x or y axis.

Part A

Determine the direction of the magnetic force along segment 1, which carries current in the -x direction.
Enter the direction of the force as a sign (+ or -) followed by a coordinate direction (x, y, or z) without spaces. For instance, if you think that the force points in the positive y direction, enter +y. If there is no magnetic force, enter 0.

Just use the right hand rule (for all parts in this problem).

+y

Part B

Determine the direction of the magnetic force along segment 2, which carries current in the -z direction.
Enter the direction of the force as asign (+ or -) followed by a coordinate direction (x, y, or z) without spaces. For instance, if you think that the force points in the positive y direction, enter +y. If there is no magnetic force, enter 0.

Just use the right hand rule (for all parts in this problem).

0

Part C

Determine the direction of the magnetic force along segment 3, which carries current in the +y direction.
Enter the direction of the force as a sign (+ or -) followed by a coordinate direction (x, y, or z) without spaces. For instance, if you think that the force points in the positive y direction, enter +y. If there is no magnetic force, enter 0.
