www.webassign net/web/Student/Assignment-Responses/submit?dep 11 82835 Two long, parallel conductors, separated by 130 cm, carry currents in the same direction. Ihe first wire ourries aourrent 4.DoA and the second carries 800 A. figure below. Assume the conductors (See in the plane of the page.) (a) what is the magnetic field created by l, at the location of I? (b) What is the force per unit length exerted by on (c) What is the magnetic field oreated by 1 at the location of (d) What is the force per length exerted by uz on In the direction in the ecton in y direction ung straight wie is 6 A and the wire lies in the plane of he rectaroular loop, which carries a current 20.0 A. The dimensions in the figure are c aloo m, and dreotian of the net foro exerted on the loop by the magnetic s taeated br the wie in z rectionExplanation / Answer
A.
Note that for a long wire of current,
B = uo I / [2 pi r]
where I is the curren source, r is the distance from that current.
Thus,
B = 6.15*10^-6 T, +z direction [ANSWER]
***************
B.
Note that
F/L = B I'
where I' is the current in the in the wire experiencing the field. Thus, I' = I2 = 8.00 A.
F/L = 4.92*10^-5 N/m, -y direction [ANSWER]
****************
c.
Note that for a long wire of current,
B = uo I / [2 pi r]
where I is the curren source, r is the distance from that current.
Thus, I here is I2 = 8.00 A,
B = 1.23*10^-5 T, -z direction [ANSWER]
****************
B.
Note that
F/L = B I'
where I' is the current in the in the wire experiencing the field. Thus, I' = I1 = 4.00 A.
F/L = 4.92*10^-5 N/m, +y direction [ANSWER]
