I have this question here that I'm having a little difficulty working out, I can't quite figure out if I'm correct.
The question has multiple parts, most of which I have worked out, I'm just making sure I have my facts down right.
------------------------------------
The illustration below shows a current carrying wire between magnetic poles. The arrows in the picture show the direction of the current.
P1):
In the illustration, will side x be forced up, turning out of the page, or down, turning into the page?
A1):
Side x would be forced down into the page.(I think)
P2):
How far will the wire rotate before it stops? Why?
A2):
It should rotate until it is perpendicular with the magnetic field.(Not too sure about this one.)
P3):
How could you cause the wire in the illustration to continue to rotate after it stops?
A3):
reverse the current at every half turn.
Thank you!
