Question

A. Out of the page B. To the right C. To the left D. Downwards to the bottom of the page. E. Upwards to the top of the page. F. Into the page AT ngid wire in the shape of a rectangular loop is shown below A rigid wire (The surface of the loop is perpendicular to the page.) Current flows around the loop going through section 2 from bo ttom to top, through section 3 into the page, and so forth. Determine if the force on each section of the rectangular loop is zero. If not zero, determine the direction of the magnetic orce on that section. (Ignore the forces on the two vertical wires that connect the loop to the bottom circuit with the battery and switch.) Then decide the net effect of these forces on the loo 2

Explanation / Answer

here,

for the rectangular wire

as F = I * L X B

for wire 1

using right hand rule

the net magnetic force is D) downwards

for wire 2

using right hand rule

the net force is A) out of the page

for wire 3

using right hand rule

the net magnetic force is E) upwards

for wire 4

using right hand rule

the net magnetic force is F) into the page

F1 = - F3 and F2 = -F4

so,

the net force on the rectangular loop is zero or the force may distort the loop
