--- Quote from: Dibss on May 09, 2010, 01:33:46 pm ---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.

Look at the picture. As the current is travelling downwards there is a south pole induced on both.


Wouldnt that cause repulsion ?

Dibss:
@ari
hope the diagram helps...
although i'm not really an expert at explaining and could be making a mistake :/ could someone check this?
