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 ...

Peculiar bursts of energy called chorus waves have been detected in deep space far from our planet, suggesting they could ...

Chorus waves are mysterious, chirping signals produced by spiraling plasma inside our planet's magnetic field. But a new detection suggests scientists may understand less about them than first thought ...

If you need help visualizing magnetic fields, these slow-motion video captures ... for a person used to a bar magnet. We should advise you before you watch the video below the break, if you ...

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 ...

Because Earth's magnetic field is slightly asymmetrical and more complex than that of a regular bar magnet, the magnetic south pole — the point in the Southern Hemisphere where the magnetic ...

Physics is a subject that demands regular and consistent practice. In order to master the concepts and formulas, students ...
