This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

Cutting a bar magnet in half won't get rid of its poles ... director of the National High Magnetic Field Laboratory in Tallahassee, Florida. While people have been using magnets for thousands ...

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 ...

Earth's magnetic field can be visualized if you imagine a large bar magnet inside our planet, roughly aligned with Earth's axis. Each end of the magnet lies relatively close (about 10 degrees ...

Given the importance of this gargantuan bar magnet in our day-to-day lives, it’s worth understanding how it works — and when it doesn’t. Since the magnetic field is sustained by geological activity ...

That magnet is strong, representing roughly 75 percent of the intensity of Earth's magnetic field at the surface. Of course, a bar magnet is not a perfect representation — it's actually electric ...

This movement produces an electrical current that generates and maintains the strong magnetic field around the planet. The field has two opposite poles located at the north and south of the planet, ...

In a recently published article in IEEE Electron Devices Magazine the authors, I was one of them, looked at the impact of external magnetic fields on spin tunnel torque magnetic random-access ...
