Question
I For parts (b) - (d), assume the wire carries a current directed out of the page.
(b) What is the direction of the magnetic field generated by the wire at point 1?
_____
Explanation / Answer
a) B=mu not*I/(2*phi*r)=2*10^-7*4.9/0.13=7.5384*10^-6
b) Along tangent to the circle in counter clockwise direction( 90 degrees to the wire).
c) Along tangent to the circle in counter clockwise direction (90 degrees to the wire).
d) Along tangent to the circle in counter clockwise direction (90 degrees to the wire).
II)
when the wire carries a current directed into the page.
e) Along tangent to the circle in clockwise direction( 90 degrees to the wire).
f) Along tangent to the circle in clockwise direction (90 degrees to the wire).
g) Along tangent to the circle in clockwise direction (90 degrees to the wire).
