Understand the magnetic field of two long wires with this detailed physics example! Learn how currents interact, how to calculate the resulting magnetic field, and visualize the principles behind ...
For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...
Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...
