Please show drawing, steps, and explain. I was absent for this chapter due to the flu :(

Each current-carry wire shown below is immersed in a uniform B-field directed toward the BOTTOM OF THE PAGE. (The B-field is omitted from the diagrams for clarity.) In which direction is the magnitude force that acts on each wire? Be precise. If no force acts, write "none." If B = 7.5 times 10-5 T (close to the strength of the Earth's field near the Earth's surface) and I = 12 A for every wire in the problem above (a typical current drawn by a large household appliance) calculate the magnitude of the net magnetic force that acts on the wires in parts (d), (e), and (f). Each wire has a length of 100.cm. Show your work completely for EACH.

Explanation / Answer

3)

a) perpendicularly in to the paper plane

b) none

c) towards left (-x axis)

d) to wards right (+x axis)

e) perpendicularly out of the paper plane

f) perpendicularly in to the paper plane

4)
d) F = B*i*L*sin(90) = 7.5*10^-5*12*1 = 9*10^-4 N

e) F = B*i*L*sin(90-15) = 7.5*10^-5*12*1 = 8.69*10^-4 N

f) F = B*i*L*sin(90-55) = 7.5*10^-5*12*1 = 5.16*10^-4 N
