Question

4. Current I1 is 5 A, and current I2 is 10 A. The distance d between the wires is 10 cm.

a) What is the direction of the magnetic field current I1 generates at point A? Circle your choice... 1. into the page, 2. out of the page, 3. to the left, 4. to the right

b) What is its magnitude?

c) What is the magnitude of the magnetic force that current I1 exerts on the 1m-long element of wire with current I2? Use the results from b).

d) What is the direction of that force? Circle your choice... 1. top of the page, 2. bottom of the page, 3. left, 4. right

Explanation / Answer

I1 = 5 A,I2 =10 A, d =10 cm, L = 1m, uo=4pi*10^-7 T.m/A

a) into the page

(b) B = uoi1/2pi*d = (2*10^-7*5)/(0.1) =10^-5 T

(c) F = i2LB = 10*1*10^-5 = 10^-4 N

(d) top of the page
