When currents in wires run parallel, the wires attract due to the magnetic fields from the currents and the Lorentz force. The currents can also be run anti-parallel, making the wires repel. Place the ...

One problem down, x - 1 problems go There are plenty of reasons why fusion energy has yet to become reality, but according to ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer ...

It doesn’t, really. The wire vaporizes into plasma, and if the pulse is fast enough, the Lorentz force hold the plasma together. The rest is non-trivial high-voltage engineering. The original ...
