- TL;DR Summary
- The prediction of a force between perpendicular wires distinguishes two very different kinds of electromagnetism.
I think everyone would agree that linear current is simpler than circular current. So please tell me honestly, which one do you think is more fundamental? Considering that a loop is made up of closed lines, I think the answer is obvious.
What is painful is, in mainstream electromagnetism, the magnetic field generated by a circular current is considered a fundamental phenomenon, and the so-called "magnetic field" always implies that at least one of the interacting parties is a circular current.
Now you might be tempted to say that even if we construct electromagnetism with linear current as the basic phenomenon, what we end up with is not fundamentally different from what we use now.
But that is simply not true.
Consider this situation, two straight wires carrying current are perpendicular to each other.
Don't tell me that any current formation requires a closed circuit. As long as the rest of the two circuits are far enough apart, the effect of the rest of the circuits can be ignored.
Mainstream theory predicts that if I1 is fixed,I2 will rotate counterclockwise around the intersection point. However, this can easily lead to many paradoxes. Here is one.
With something like a track providing the centripetal force, there is nothing in mainstream electromagnetism that can prevent BC from circling around A and accelerating forever. Therefore, it violates another mainstream belief: the law of conservation of energy.
Here are three questions I propose.

- Has the force between perpendicular wires been measured experimentally in history?
- If not, why does everyone take the predictions of the mainstream theory as fact?
- How do you resolve my paradox?
