It is a common grade school experiment to wind some wire around a screw, power it up, and watch it pick up paper clips or other ferrous materials. It is also grade school science to show that neither ...

In the 5th grade unit 'Magnetic Force Created by Electric Current,' the focus is on relating current and the number of turns ...

Researchers have shown that a pair of vertically arranged electromagnets can levitate and steer a magnetic robot inside a ...

The lifting electromagnet article I posted years ago (https://www.codrey.com/electronic-circuits/lifting-electromagnet-diy/) has been more popular that it should have ...

One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the U.S. Department of Energy's Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from ...

Why did the 50-foot-wide electromagnet cross half the country? To help physicists discover new subatomic particles, of course. Mounted atop a 64-wheel trailer, a massive superconducting circular ...

Magnets like this one are great at picking up metal objects like these, but once you pick them up how do you let them go? For that you need a special type of magnet – an electromagnet. Magnetism and ...
