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 ...

If you need help visualizing magnetic fields, these slow-motion video captures ... for a person used to a bar magnet. We should advise you before you watch the video below the break, if you ...

(Our planet's magnetic field should look a lot like the field around a bar magnet, but electrically charged particles in the solar wind push against the magnetic field, so the side pointing away ...

Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate 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 ...
