Using an XMC1100 microcontroller development board and a TLV49 3D magnetic sensor, the device is able to track the poles of a magnet in real-time and produce an approximation of what the field ...

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 ...

Instead, magnetic north is the changing location where the planet’s magnetic field lines converge. This field is generated by the churning of the planet’s outer core, a layer of molten iron and nickel ...
