Witness the experiment, we elevate the classic Lego concept by creating a completely silent, levitating fan using magnets and a simple circuit. A reed switch detects magnetic fields and sends pulses ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but ...

Warwick Acoustics' electrostatic speaker uses 90 percent less energy and saves up to 20 miles of range. But on which EV will it debut?

you’ll find a coil of copper wire. When you plug it in, the electric current passing through this coil generates a magnetic field. Meanwhile, phones that support wireless charging include a coil ...

Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions ...

A team of scientists from Princeton University has measured the energies of electrons in a new class of quantum materials and has found them to follow a fractal pattern. Fractals are self ...

The earth’s magnetic field is made up of molten iron and another element called geodynamo, which then creates the magnetic field within the earth’s outer core. Therefore, this movement can be affected ...
