A curious topological structure known as a hopfion ring has been induced in a magnetic ... changing the direction of an external magnetic field, which was weak enough that the skyrmion strings ...

The deflection angle of the needle is noted for varying distances of the magnet, and with some quick math the local field strength of the Earth’s magnetic field can be calculated based on the ...

We can learn a lot from studying the rings inside trees ... These endpoints are where the magnet is the strongest. You can picture the magnetic field like arched lines that leave the north ...

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 ...

It’s a simple magnetic ring attached to a non-magnetic finger ring that doubles as a kickstand. But what if both rings were magnetic? What if both of them were the same size? What if each of ...
