A long straight wire carries a current I1 = 15A and has a length 1.1m. (a) What is the magnetic field created by this wire a distance of 0.1m away? (b) A second wire has the same length and carries a current I2 = 5A in the same direction as the first wire. If this wire is placed 0.1m away from the first, what is the force it experiences? In what direction is the force on the second wire?

a) 2.95*10^{-5}T

b) 1.65*10^{-4}N

Step-by-step explanation:

(a) The magnetic field produce by a finite wire, in a poin perpendicular to the center of the wire, is given by

   (1)

where I is the current, R is the distance to the wire and phi is the angle between the center of the wire until the top. The number 2 before the integral is because of the symmetry.

In this case we have, by geometry:

Hence, by replacing in (1) we obtain:

(b) The magnetic force of two wires is given by:

hope this helps!!

step-by-step explanation:

i took the test: )

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant
