A square current loop of edge length L = 0.31 m with I = 5.5 A is pulled from a

Q: A square current loop of edge length L = 0.31 m with I = 5.5 A is pulled from a

a) by using lenz's law the direction of the magnetic force on the loop is to the left b) F = B * I * L=1.7 * 5.5 * 0.31 = 2.89 N the magnitude of the magnetic force on the loop is 2.89 N c) for this we also use the lenz's law so the direction of the magnetic force is to the right

Question

A square current loop of edge length L = 0.31 m with I = 5.5 A is pulled from a region where the magnetic field is zero into a region where the magnetic field is perpendicular to the loop with a magnitude B = 1.7 T (see figure below).

(a) What is the direction of the magnetic force on the loop?

to the right, to the left, to the top of the page, to the bottom of the page

(b) What is the magnitude of the magnetic force on the loop?
N

(c) If the loop's velocity is reversed, what is the direction of the magnetic force?

to the right, to the left, to the top of the page, to the bottom of the page

Explanation / Answer

by using lenz's law

the direction of the magnetic force on the loop is to the left

F = B * I * L=1.7 * 5.5 * 0.31 = 2.89 N

the magnitude of the magnetic force on the loop is 2.89 N

for this we also use the lenz's law

so the direction of the magnetic force is to the right
