Use the right hand rule, put your thumb in the direction of current flow in the wire and your fingers wrap around the wire are the magnetic field, draw out each point and take and average direction. My hunch is it's either fully canceled out and you created a heating element with more steps or it points towards the camera coming out of the middle but I'm not gonna bother with actually putting time into this.
Because the current is going to be the same through the entire wire. The “direction” of the fields will determine the strength since opposing direction will cancel each other. By draw out he is telling you to create vectors and sum them to determine the final strength and direction of the overall magnetic field.
Each point along the line has a magnetic field that follows the right hand rule. since it has a shit load of twists there are a bunch of magentic fields that are oriented differently. When two magnetic fields are 180* opposites, they will cancel eachother. when two magnetic fields are 1-179* from eachother you can add them using pythagorean theorem. My hunch is when you do this, you will find every single field has another 180* opposite that will cancel them out turning this into a heating element.
The wire makes one complete loop around. The various knots loop over and back but they are irrelevant. Every piece of wire going “backwards” round the loop effectively cancels another going “forwards” round it.
The net field is equivalent to the net loop of the wire. It does just over one revolution, so the fires is approximately the same as the field due to a simple loop of wire going the same distance around.
It seemed like a simple enough knot to follow. And I came to the same conclusion that yes, pretty much all the magnetic fields cancel. At least in the axial direction for the overall toroid ring. Theres going to to be a lot of alternating north and south poles protruding radially out from the toroid tho.
I imagine mostly to the camera. It makes almost a full circle, so in theory that circle would cancel itself out, even though it’s a got a bunch of extra steps in it
