GCSE; CCEA Double Award; Magnetic fields - CCEA Magnetic field of a bar magnet. Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents.

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

It looks the same as my older cow magnets but they do not have a magnetic field similar to a bar magnet. Rhett Allain is an associate professor of physics at Southeastern Louisiana University.

The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...

The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged ...

Imagine a bar magnet inside Earth, more or less aligned with the axis, ... About 75 percent of the intensity of Earth's magnetic field is represented by the "magnetic bar." ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...

We Earthlings see the sun every day of our lives—but gaining a truly new view of our star is a rare and precious thing. So ...

Earth’s magnetic field is a dipole field with two poles, like a bar magnet. When the poles flip, it could cause chaos for future humans.

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

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 ...

But unlike Earth’s magnetic field or that of a bar magnet, the sun’s magnetism is patchy and highly fluid, even during its dipole stage. “It’s not uniformly positive,” says Todd Hoeksema ...
