Learn about and revise magnets, magnetic poles, magnetic fields, permanent and induced magnets with GCSE Bitesize Physics.

Just as we use electric field lines to represent the electric field created by charges, we can draw magnetic field lines to represent the magnetic field created by magnets.

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

If we draw magnetic field lines around a magnet, we always see the lines curve around, joining the two poles. A regular, two-poled magnet. Wikimedia Commons ...

The magnetic field will create a "sideways" change in electric potential across the material - which you can measure. Using this change in potential and the size of the material, you get the ...

And, although our galaxy’s magnetic field is incredibly weak, it still plays a powerful role in shaping the universe.

Every magnet that we have ever observed is a dipole — it has both a north and south pole. If we draw magnetic field lines around a magnet, we always see the lines curve around, joining the two ...

The sun’s powerful magnetic field has long puzzled scientists. A new study suggests the source of its magnetic field is nearer the surface than first thought.

The images map out properties such as fractal density and magnetic field lines. The interstellar medium in our Milky Way galaxy is magnetic, can be compressed, and is turbulent.
