The basics of ferromagnetism
Magnetism is the force that is exerted by magnets when they repel or attract each other. It is caused by the motion of electric charges. Electrons can spin like tops, and they orbit

- Physicists discover a copper-free high-temperature superconducting oxideEngineers have designed and synthesized a groundbreaking new material -- a copper-free superconducting oxide -- capable of superconducting at approximately 40 Kelvin, or about minus 233 degrees Celsius, under ambient pressure.
- A lighter, smarter magnetoreceptive electronic skinImagine navigating a virtual reality with contact lenses or operating your smartphone under water: This and more could soon be a reality thanks to innovative e-skins. A research team has developed an electronic skin that detects and precisely tracks magnetic fields with a single global sensor. This artificial skin is not only light, transparent and […]
- E-scooter crashes mainly caused by reckless drivingCrashes on electric scooters are mostly due to the behavior of the riders, with one-handed steering and riding in a group being some of the largest risk factors. The researchers are also concerned about riders who deliberately crash or cause dangerous situations when riding, a phenomenon that seems to be specific to electric scooters.
- These electronics-free robots can walk right off the 3D-printerThis a robot can walk, without electronics, and only with the addition of a cartridge of compressed gas, right off the 3D-printer. It can also be printed in one go, from one material.
- Good vibrations: Scientists discover a groundbreaking method for exciting phonon-polaritonsNewly published research demonstrates a novel way of generating phonon-polaritons by making electrons collide with crystal lattice structures. The discovery paves the way for cheaper, smaller long-wave infrared light sources and more efficient device cooling.
- New platform lets anyone rapidly prototype large, sturdy interactive structuresA rapid prototyping platform called VIK (Voxel Invention Kit) enables makers without engineering expertise to create large-scale interactive devices using a series of reconfigurable electromechanical building blocks. These user-friendly components can be assembled using only a soldering iron and a pair of pliers.
