The artificial 'meta-materials' studied by the researchers consist of very small U-shaped metal 'nano-rings'. The electromagnetic field of light drives charges back and forth, thereby inducing an ...

Invented in 1824 by the British physicist William Sturgeon, electromagnets are a fixture of modern life, appearing in loudspeakers, motors, magnetic resonance imaging (MRI) machines, maglev trains, ...

Imagine if we could use strong electromagnetic fields to manipulate the local properties of spacetime—this could have important ramifications in terms of science and engineering. Electromagnetism has ...

Using the strongest materials known to man, scientists are building the most powerful electromagnet in the world — one that won't blow up a split second after it's turned on. Subscribe to read this ...

Key learning points Properties of magnets What are magnetic fields? Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, ...
