THE electromagnet designed for the use of oculists by Dr. Haab, director of the Zurich eye clinic, and shown in the accompanying photographs, is the most powerful and efficient apparatus of this ...

Electromagnets use electric current to generate a magnetic field which can be turned on or off as needed. They are made from a softer iron which quickly dissipates the induced magnetism after the ...

It’s an electromagnet pendulum analog circuit. Whether you’re building it, or just studying the schematics, this is a fun way to brush up on the non-digital side of the craft. The pendulum is ...

The one that [Made in Poland] chose to sacrifice was particularly nasty and greasy, but after popping off the pulley, the treasure within was revealed: the large, ring-shaped clutch electromagnet.

The questions in this quiz are suitable for GCSE combined science students studying electromagnets, the motor effect, Fleming’s left hand rule, and electric motors. If you struggled with the ...

Automatic knuckle couplers have been a part of model railroading for more than 60 years. Not only do these couplers look more like what you see on full-size locomotives and freight cars, they're easy ...

In a telegraph a switch opens and closes an electric circuit. In Morse's original design, the receiving device used an electromagnet, powered by the electric current in the circuit, to raise and ...

A normal-conducting resistive electromagnet would have an electrical power of over one megawatt and, as it would have to operate continuously, its power consumption would be high. Hence the idea ...

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 ...
