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 ...

The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how ...

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 ...

They sense weak magnetic fields via gaseous forms of alkali metals, such as rubidium or caesium. Within the devices these atoms behave like tiny magnets and are aligned with a beam of laser light ...
