Here's why: the 15-ton electromagnet can't just be disassembled ... Given that it's ten times cheaper to move the magnet than it is to build a new one, researchers will take their chances ...

What Is an Electromagnet? There are essentially two ways to make a constant magnetic field. The first is with a permanent magnet, like those things that stick to your refrigerator door.

There are much better explanations online. In these times, you don’t need to build a lifting electromagnet driver circuit using discrete components for your hobby projects because there are countless ...

Adult supervision and safety goggles are required. What is an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field ...

All you need to know is that there are some guys in a truck next to a police building with some evidence in it. The truck guys crank up a huge electromagnet to destroy the evidence. Could you ...

This is achieved with a U-shaped electromagnet. The polarity of a driving ... the reason [Mike] is studying these so closely is that he wants to build a different driver circuit to have better ...

While technically not an electromagnet, it is possible to build a similar device that will weakly pull on copper and aluminum, and [Cylo] shows us how it works in a recent video you can see below.
