auestion 4. Wire and Loop [17 points] Section: A loop of wire with a current l is placed next to a very long wire with current 1 located 12. li 0.3 Amps and l2 8 Amps; The loop is a length o 2 meters from the wire and has a width of 0.25 m and of 0.6 m. A. [4 points] Determine the direction of the magnetic field from the straight wire (I2) on either side of the straight wire. Explain. 0.2 m B. [4 points] Determine the direction of the force on each of the four segments of the loop of wire. Explain. c. [5 points] calculate the net force on wire loop. Show all work. 0.25 m

Explanation / Answer

A) direction of magnetic field on all the sides is into the page

B) left side (end towards i2) will have force towards right as F= iL x B   and B is into the page, L is towards current.

bottom side will have upward force, rightside will have leftward, top side will have downward.

C) top and bottom forces will cancel each out as both have same magnetic field.

   F = (uoi2/(2pi*0.2)) *i1*0.6 - (uoi2/(2pi*0.45)) *i1*0.6

      = 2e-7*0.3*8*3 - 2e-7*0.3*8*0.6/0.45

     = 8*10^-7 N answer
