How does a magnetic compass work? Well, it’s all down to basic physics and human ingenuity. The key component of a standard baseplate compass is its magnetized needle, which is allowed to spin freely ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

Picture yourself standing at the Geographic North Pole with a compass in your hand. You'd expect that trusty needle to point ...

Earth’s magnetic field has been acting restless, with the north magnetic pole racing across the Arctic and the field itself ...

Magnetic north has never sat still. In the last hundred years or so, the direction in which our compasses steadfastly point has lumbered ever northward, driven by Earth's churning liquid outer core ...

When the sun reaches its period of peak activity, known as solar maximum, our star's magentic field will suddenly reverse. But why does it happen, and will it impact Earth? When you purchase through ...

Magnetic force microscopy (MFM) is one of the modes of scanning probe microscopy (SPM). As the name implies, it is used to map magnetic characteristics. MFM investigates the local magnetic fields at ...
