Web11 dec. 2024 · To cut a long story short, the current flowing in the wire produces a magnetic field in the points of the green circle, that is not zero. What is identically zero … WebSo the force from current 2 on wire 1 of length L1, from here to here, is equal to current 1 times L1-- which is a vector-- cross the magnetic field created by current 2. And so we can do the same cross product here. Put our index finger in the direction of L1. That's what you do with the first element of the cross product.
WebFor conventional current flowing through a straight wire, this can be found by the right-hand rule. Imagine gripping your right hand around the wire with your thumb pointing in the current direction to use this rule. The fingers show the direction of the magnetic field, which wraps around the wire.
