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

Detecting magnetic fields A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate.

How Does A Biological Geomagnetic Sense Work? The Earth is surrounded by a magnetic field, generated by the movement of the planet’s liquid core. It’s why a magnetic compass points north. At Earth’s ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.

Earth’s Magnetic Field Could Take Longer to Flip Than Previously Thought New research suggests a polarity reversal of the planet takes about 22,000 years, significantly longer than former estimates ...

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 ...

Mercury’s magnetic field is 150 times weaker than that of our planet, however. This has recently been confirmed by the Nasa space probe Messenger. How can the large discrepancy in the field strength ...

Illustration of the global coronal magnetic field as the sun rotates. The background is the solar corona observed in extreme-ultraviolet waveband, with global coronal magnetic field maps measured ...

Magnetic Field Formula: Explore the fundamental principles of magnetic fields, including their formulas, properties, and diverse applications. Learn how magnetic fields influence everyday life and ...
