Magnetic monopoles at room temperature

Magnets have two poles. One north and one south pole. Different poles attract each other, and equal poles repel each other. No matter how you cut a magnet, you always end up with two poles in each piece.
But scientists have longed theorized that magnetic monopoles (just a north or a south pole) should be possible, since in electricity, doing a parallel with electric charges, you can have for example a single negative charge, an electron, or a positive charge, a proton.
Some time ago scientists produced the first "monopole-like" nano structures at freezing temperatures.
Now scientists from London have created the first magnetic monopoles at room temperature.

You can read more about this on the related news page of the Imperial College of London.
Or watch a video from the scientists involved explaining it here.
