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 ...

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 ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

Juvenile loggerhead turtles swim into oncoming ocean currents, instead of passively drifting with them. After loggerhead turtle hatchlings leave nesting beaches, they live in the ocean for 7-12 years ...

In Part 1 of this series, we covered the fundamental concepts and principles incorporated by flow meters along with various flow measurement methods used in mechanical flow meters. It covered in depth ...

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 ...
