Hi all, the question is in regards to magnetic fields in a wire. Please refer to illustration below to understand my question. (https://www.imageupload.co.uk/image/B9f1) As you can see in Picture 3 two wires parallel to each other will attract each other if the current is going in the same direction. How does attraction occur? Why don't the wires repel each other since the wire acts like a magnet with the same dipoles parallel to other. For example. t's like 2 magnetic dipoles north and south parallel to each other. If we apply this same scenario but the wire is a magnet on a horizontal plane it makes sense but as you can see in picture 1 this is not correct. In picture 1 if the wire was a magnet on a horizontal plane why doesn't it show the results of picture 2? Thank you in advance and sorry if it's a silly question. I'm really struggling figuring it out and I know there are smart people on this forum.
