Question

A long, straight wire (see the figure below) carries current

I1 = 3.1 A

and is a distance

h = 15 cm

from a rectangular current loop that carries a current

I2 = 1.58 A.

(a) If the loop has length

L = 54 cm

and width

w = 30 cm,

what are the magnitude and direction of the force exerted by the wire on the loop?

(b) What is the force exerted by the current loop on the wire?

magnitude     1 N direction     2---Select---toward the long straight wireaway from the long straight wireto the leftto the right w 2 l

Explanation / Answer

Forec exerted by long wire = ( 3.1) ((1.58) ((0.54) ( 4pi x 10^-7 ) / 2pi x 0.15 - ( 3.1) ((1.58) ((0.54) ( 4pi x 10^-7 ) / 2pi x [ 0.15 +0.3) + 0 + 0= 5.28984 x 10^-7 ( 6.667 - 2.222) = 23.512 x 10^-7 N

b) direction = towards the long staright wire

c)it should be same

d) Direction = away from the long staright wire
