correct answers to all parts would be greatly appreciated!
3) [70 points] In this figure, "N" and "S represent the north pole and south pole of a magnet, that produces a magnetic field of 0.035 T at the position of the 5-A current. The current lies on this page, and makes 20° above tx-axis a) Draw Bi in the diagram, then determine the magnitude and direction of the magnetic force on the 12-cm length of the wire. b) Determine only the direction of the magnetic force on the wire if the he current is changed to - z-axis ('into the page" (x)).Explanation / Answer
a)
We know that
F =BILsintheta
=(0.035)(5)(0.12)sin20 =7.18*10-3N
b)
From the right hand thumb rule we can say that if the direction of current is in the -z direction and magnetic field in the -x diretion then magneticforce will be in the -ydirection.
