Question

a. Each current-carrying wire shown above is immersed in a uniform B-field directed toward the top of the page. In which direction is the magnetic force that acts on each wire? Please be precise.

b. If B = 7.5 x 10^-5 T, and I = 11 A for every wire shown above, 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 95 cm. Please show work, and reasoning.

Each current-carrying wire shown above is immersed in a uniform B-field directed toward the top of the page. In which direction is the magnetic force that acts on each wire? Please be precise. If B = 7.5 times 10^-5 T, and I = 11 A for every wire shown above, 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 95 cm. Please show work, and reasoning.

Explanation / Answer

a)

a.out of the page

b. zero

c.right side

d.left side

e.in to the page

f.out of the page

b)

FD = B*i*L*sin(theta) = 7.5*10^-5*11*0.95*sin(90) = 7.8375*10^-4 N

FE = B*i*L*sin(theta) = 7.5*10^-5*11*0.95*sin(75) = 7.57*10^-4 N

FF = B*i*L*sin(theta) = 7.5*10^-5*11*0.95*sin(35) = 4.4954*10^-4 N
