I've tried to find this repeatedly in my textbook, but my teacher told us to ignore the book and then didn't do a great job explaining it, but here goes...
A conventional current is flowing into the page (-Z direction) along a straight wire placed at the origin O perpendicular to the page. (see attachment)
Question 1: The magnetic field due to the current at P will be in the direction of: +X, -X, +Y, -Y, or +Z?
Using the right hand rule I got -Y direction. Is this correct?
Question 2: If there was a second, straight wire, carrying a current, at P (perpendicular to the page), where the current is in the +Z direction (out of the page), what is the direction of magnetic force on this 2nd wire? The choices are: +X, -X, +Y, -Y, or -Z
My guess is +X, but I'm not confident with that answer. I know there is another right hand rule to use here, but i don't get how it works. Can someone answer and explain?
Thank you.
