Equipment: Two square U-shaped wires, a Plexiglas frame and a Xantrex HPD 15-20 power supply. What it does: The current carrying wires attract and snap together or repel each other depending on the ...
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 ...
A magnetic field will apply a force on a single moving charge, and it will also exert a force on a current on which is a collection of moving charges. The force encountered by a wire of length l ...
