The question:
Two parallel cuurent-carrying conductors are next to each other. The one on the right (first one) has current travelling up the page while the other has current travelling down. Determine whether the conductors attract or repel each other. Explain your reasoning.

I know the answer but don't know if i expressed the answer properly.

Answer: they repel. The first conductor's magnetic field causes the second conductor to experience a force to the right and vice versa for the second conductor.
is my use of vice versa correct? does vice versa mean opposite for everything, or for the first thing (subject) mentioned?

also how do you express tesla in terms of N, m, s and C. I couldn't find it in the text books
thanks

I dont think that usage is right, it just doesn't sound correct. It would be safer to write it out fully.

to simplify, the fields created in the space between the wires are in the same direction, causing a repulsion between the wires.

F=qvB so B=F/qv
.'.1 T = 1 NsC^-1m^-1

Would be best to draw a diagram.

Like viewing the wire conductor from the end view draw the magnetic field likes around it.

You will be able to see that currents in the same direction will attract and currents in the opposite directions will repel.

If you don't know what I mean, I think I can scan a picture for you

no, i just wanted to know how to answer it properly in words, think Constip8edSkunk's answers is best so far
but tell me, did i use vice versa correctly?

is that from prelim?

"The first conductor's magnetic field causes the second conductor to experience a force to the right and vice versa" means the 1st push the 2nd to the right and the 2nd push the 1st to the right, i think. so i dun think its really right. perhaps instead of saying' to the right', say 'away' ...or something


can't remember, but im pretty sure its in the hsc course: "F=qvBsin@" where @ is the angle of the v velctor with the field

i knew i had something wrong with use of vice versa, it sounded odd

can't remember, but im pretty sure its in the hsc course: "F=qvBsin@" where @ is the angle of the v velctor with the field hmmm, maybe it's another variation of "F= BIlsin@"

i should check my prelim
