It is also grade school science to show that neither an electromagnet nor a permanent magnet will pick up nonferrous items like copper or aluminum. While technically not an electromagnet ...

The bigger the current the stronger the magnetic field and hence the stronger the electromagnet. Hazard Consequence Control measures Water Electric shock Do not set up the experiment near taps ...

Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the ...

For that you need a special type of magnet – an electromagnet. Magnetism and electricity are very closely related. If a magnet is moving near to a wire it will generate an electric current and ...
