 This video is an attempt to talk about the forces on two parallel wires due to the interactions between the magnetic field and the current. I have one example in the video that talked about the equation where I stepped through some of the directions, but I want to try and do it using my 3D models here. Now again, this is going to be kind of rough because I'm trying to work with the camera and the models and everything else. But as we talked about in some of our other videos, when you have a current which is moving in that direction, then the magnetic field will wrap around like it is for your right hand. So that means it would come out, crossed, and then back in. Which means we've got out, across, and back in. And again, that should fit with what we're seeing here. So we've got our little arrows there showing us that the current is moving to the right and the magnetic field from that one comes out on the top, down, and then in on the bottom. And if our currents are going in the same direction, you actually have the same pattern for this one, for the blue field here. Now what's happening then is you end up having magnetic field due to the green line at the location of the blue line. And there you can see that it's going in. And so we have a magnetic field going in where I've got the blue current towards the right. Now I'm going to go ahead and move the blue magnetic field off here so we can focus just on the magnetic field due to the green wire, the top wire. So at that location, you've got a current moving towards the right and a magnetic field which is in. Now I'm going to have to actually stand up here in order to get this to go. But you've got a current towards the right. Your magnetic field is going in. That tells me that the force would be upwards on that wire. So I can go ahead and add in here that my force would be up because again the current is to the right in the blue wire. The magnetic field due to the other wire is going in. That gives me an upward force. Now if I go through and I look again at the magnetic field due to the lower wire is going in down here on the bottom. It's coming out here, which means for the top wire, the magnetic field is coming out of the screen towards you while the current is going in that direction. And that tells me that that would create a downwards force. So each of the two magnetic fields pulls on the other wire and if the two wires are in the same direction, it pulls them together.
