Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough ...

Ferromagnets are characterized by a magnetization that has long been used to store information. The magnetization is largely due to localized electron spins with their associated magnetic moments ...

To see a video on this topic by the author, click here. However, as the frequency increases; the current moves toward the outside of the conductor as indicated by the red and orange colors. This ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

Large-scale currents are the conveyor belts of the ocean, transporting water and nutrients and controlling Earth's climate.

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...
