Strange metals challenge the 60-year-old theory that electric current consists of a flow of discrete charges. Strange metals ...

Batteries are a part of our everyday life, and power everything from phones to gaming handhelds to laptops, but do those ...

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...

Current electricity is a flow of electrons that moves along a continuous and closed path called a circuit. Electric current flows easily through certain materials called conductors. Almost all ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

Originally, current was defined as the flow of charge from positive to negative. Scientists later discovered that current is actually the flow of electrons, from negative to positive. The original ...

Compare fluid metering and solenoid pumps to determine which delivers the best performance for your specific fluid delivery ...
