All the magnets we’ve ever seen have a north and a south, but there might be some out there that have only one end.
Physicists have theorised about the existence of a magnetic monopole for decades, but we have yet to find one.

The speed comparison between today's technology and femtosecond spintronics is like comparing the fastest bullet train on Earth to the speed of light.
Four identical NASA spacecraft fly near the sun-facing boundary of Earth’s magnetic field (the blue wavy lines).
After half a century of trying, scientists have finally caught a glimpse of the magnetic process that fuels space weather and the northern lights.
Spin, liquid – just add quantum.
Here's how they could revolutionise science.
You may want to be careful with that, Darth!
Warning: you'll never watch a lightsaber duel in the same way again after you read this ...
Riding on air.
The engineers who brought this science-fiction stable to life relied on some very well established science fact.
The invisible force and visible effects of magnetism.
I have a confession: I’m obsessed with magnets. We rely on magnets every day, but seldom give them a second thought. There are magnets in your credit card, your cellphone, your car, microwave oven and…
Magnets have mysterious powers – now shown to influence heat and sound.

Sound waves are made of particles called phonons. New research shows they're affected by magnetic fields, with researchers able to steer heat magnetically.
Superconducting materials have strange and unusual properties including magnetic levitation.
Just what is a superconductor? And what can it be used for? Research using superconductors at higher temperatures opens up more possibilities for this fascinating class of materials.
Repetitive transcranial magnetic stimulation can help alleviate symptoms of autism, such as anxiety.
Around 1 in 68 children has an autism spectrum disorder (ASD), according to the US Centres for Disease Control – an extraordinarily high number. Although the prevalence rise is probably due mainly to changes…
