The current is going to the right and I use the right hand rule, and swap both the current and field against each other, and I see that the magnetic field is pointed to the left, while the direction of the current is to the right.
I tried applying the left hand rule now, but I can't get anything because these two aren't making a 90 degree angle with each other :( What am I doing wrong?
I mean the answer is 'No movement.' Is that BECAUSE of the current and magnetic field not being perpendicular to each other?
each of the vector F, B and I are cross products of the other two. The magnitude of the resulting vector is always the greatest when the other 2 are perpendicular to each other, zero magnitude when the other two are parallel, and in between there is a trigonometric relationship, for example F = BIL sin t, where t is the angle between B and I.
so that means your explanation to the lack of movement is correct ;)
I haven't but I think you're talking about the next topic I'm about to start as soon as I'm done with these questions. It's right there on the second pdf file I put up. 'Currents crossing fields', there's 'at right angles', and 'at an angle other than 90 degrees.' And there's all these components over there, so I'll come back to this after I've done that I suppose. Thank you IMMENSELY for your help! You can see I was quite confused, and now I'm not.
Just one more question,
When we were talking about finding the magnetic field strength through this set-up, you said to measure the length of the wire directly opposite the weights right? Well in the question right after the one we just did [it's there in the scanned file] the length they're telling me to consider is the sideways length. Can I use that in the regular flux density equation? Would it make any difference?
