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 ...

Deciphering the universe’s secrets is partly done through observation, but just as important are solid models of the forces ...

However, researchers at MIT have discovered that both these contradictory properties live side by side in a rare form of ...

The magnetic field around a circular loop of wire is similar to that of a bar magnet. When an electric current flows through the loop, it generates a magnetic field. Inside the loop, the magnetic ...

First let us understand what magnets are. Electromagnets work by passing electricity through a wire wrapped around an iron core. The electric current creates a magnetic field, and when the current ...

Here’s how it works. The iron-cored Earth behaves like a great magnet, generating a huge magnetic field around the planet that protects it from blasts and harmful radiation from the sun.

If you put a magnetic field near your body, it's believed things will go back to normal. Ions like calcium and potassium help your cells send signals. In tests, scientists have seen magnets change ...

Magnetic fields are common throughout outer space. Refrigerator magnets and compasses are examples of this force at work. And if you have iron shavings around, you can sprinkle some on top of a ...

A new simulation suggests a massive asteroid impact may have briefly supercharged the moon's magnetic field, leaving behind ...

much the same way iron filings can reveal the magnetic field around a magnet. The team thinks that the measured three-dimensional structure might create strong turbulence withing the ...

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 ...
