Cutting metal becomes easy and efficient with a plasma cutting machine, and building one from scratch is more feasible than ...

Explore how we’ve built our second magnetic drill, designed to offer precision, power, and stability for drilling at any angle. The key feature of this magnetic drill is its powerful electromagnet ...

In a superconducting electromagnet, such as in an MRI, superconducting wire is coiled around a core to produce magnetic fields of up to 30 tesla (600,000-times as powerful as the earth’s).

You can’t have the electromagnet pushing, like this one, and expect to not change the plane of rotation. Pulling, gently, as the ball come to the center worked in all these systems.

With another electromagnet below pushing it with a lot of force, we should see it fly up in the air. Something tells me we're going to need these. Goggle up. JOE: 3, 2, 1 and-- [snap] Whoa!

By controlling the amount of current, we can make electromagnets of any strength we want. We can even reverse the magnet’s polarity by reversing the direction of the current. Given the connection ...

These loops in turn produce their own, secondary magnetic field, thereby turning the conductive object into an electromagnet that exerts magnetic forces on the source of the original magnetic field.

Tiny electromagnets made of ultra-thin carbon When terahertz pulses strike graphene discs Date: December 4, 2023 Source: Helmholtz-Zentrum Dresden-Rossendorf ...

Each has physical controls and a screen, and each plays its role in teaching a lesson about electromagnets and sound waves, with a context of audio recording and playback.

Wind the insulated wire tightly around the nail to make an electromagnet. Set up the equipment as shown in the diagram. Adjust the power pack so that a current of 0.1 A flows.
