An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens. The wire just gets very hot and the battery loses stored internal energy – it ...
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 ...
S cientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field ...
The researchers optimized a compact induction electromagnet-driven method. By adjusting the current and magnetic flux distribution, they enhanced the liquid metal (LM) flow rate and active cooling ...
