It’s OK, you can admit it — from the time you first saw those huge electromagnetic cranes in scrap yards you’ve wanted to have one. While it may not fling around a car, parts donated from scrapped ...

In this video, the process of creating an electromagnet vise using two transformers is detailed. The steps include: - Opening ...

To protect the electromagnetic compatibility (EMC) of complex systems like aircraft and automobiles, you need a full electromagnetic (EM) model. A virtual test environment allows you to assess a ...

Using the strongest materials known to man, scientists are building the most powerful electromagnet in the world — one that won't blow up a split second after it's turned on. Subscribe to read this ...

The Egg Drop is a classic way to get students into engineering, fabrication, and experimentation. It’s a challenge to build a container to protect a raw egg from cracking when dropped from various ...

Invented in 1824 by the British physicist William Sturgeon, electromagnets are a fixture of modern life, appearing in loudspeakers, motors, magnetic resonance imaging (MRI) machines, maglev trains, ...
