Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, and where they can attract or repel other magnets. Although we ...

The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

Scientists have discovered a surprising magnetic spin phase where order and disorder mix, challenging old ideas.

The Earth’s magnetic field quietly supports life on the planet and now, for the first time, its invisible powers have been used to create new nano particles and materials. Scientists at Flinders ...

Protruding up from the center of the propeller is a small vertical ring that holds two puck-shaped neodymium permanent magnets ... by an alternating magnetic field which is externally generated ...

one with magnetic coils and another with permanent magnets around their microscope. They created a uniform magnetic field and repeatedly changed its direction. "We found that microalgal biohybrids ...

They just get stuck around the blood vessels ... with the previously developed two-magnet device, while an additional group was not exposed to any magnetic field. The authors tracked the growth ...
