ok i'm attaching a picture of the notes my teacher made me jot down at the end of the question. When 2 parallel wires carry current tin the same direction the effect of the combined magnetic field results in a force of attraction. if directions are different --> force of repulsion. 9c) says there's a current going down both wires. the attachment shows combined field causing both wires to be attracted to each other. since thick rigid wire can't move, the flexible wire ends up moving toward thick wire T1-T2.


You answer is right. That's exactly what my teacher taught me!  8)

if u still care..how my teacher tought me is

the effect is opposite to that of magnets for example

If both wires have current going downswards ( pretens its like magnets ) so north and north they are supposed to repel..but no in this case its the oposite they attract

if wires have current in opsite diretecttion..so north and south..they suposed to attract but no in this case its the opsoite they repel

cheers good revision for me :p
