A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A group of U.S.-based physicists has presented experimental evidence suggesting that electricity can be generated from the ...

If they were oppositely charged, they would attract and stick together ... This will create a magnetic field, and other wires with electric current will experience a magnetic force.

The coil is fed with AC. The magnetic field from the coil induces an opposite field in the copper ring that is out of phase with the exciting field. The two fields combine to produce a force on ...

they will attract. Earth's core contains liquid iron which moves around. Iron is magnetic so the liquid iron causes Earth to have a magnetic field. The needle of a compass is a small magnet that ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...

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 ...
