Magnetism

Researchers at Massachusetts Institute of Technology have demonstrated an entirely new form of magnetism in a synthesized crystalline material. They're calling it p-wave magnetism, and it could be the key to next-gen computer memory.

Scientists have created what they say is the world's smallest untethered flying robot, by taking a unique approach to its design. To minimize size and weight, they've moved the bot's power and control systems out of its sub-centimeter-wide body.

Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up on what they call the Inner Brushless Electrical Excitation (iBEE) motor system.

Scientists have developed the world’s strongest resistive magnet, which produced a steady magnetic field of 42 Tesla (T). The system could improve devices that use magnets, as well as enable a range of new experiments that probe electromagnetism.

As some entities identify new sources to meet the demand for rare earth materials, others are looking to new tools. Materials Nexus has designed a new rare-earth-free permanent magnet help from its AI platform – at record pace.

Magnetic levitation is used to float things like lamps and trains, but usually it requires a power source. Now, scientists in Japan have developed a way to make a floating platform that requires no external power, out of regular old graphite.

Scientists have confirmed the existence of a strange new form of magnetism. Hiding right under our noses, the team says that “altermagnetism” can be found in everyday materials and could have major technological uses.

When it comes to the treatment of Parkinson's disease, electrical deep brain stimulation (DBS) is a commonly used technique. It does have some drawbacks, however, which is why scientists are now looking to tiny wirelessly activated magnets instead.

Scientists at ETH Zurich have discovered a new type of magnetism. Experiments show that an artificially produced material becomes magnetic through a mechanism that hasn’t been seen before.

GM is looking to Niron Magnetics to help it eliminate problematic rare earth materials from its permanent magnet EV motors. Niron's "Clean Earth" magnets are claimed to be the only rare-earth-free permanent magnets capable of automotive-grade power.

The skin ulcers that diabetics often develop on their feet are slow to heal, sometimes to the point that they become infected and require foot amputation. A magnetic gel could keep that from happening, as it triples the healing speed of such wounds.

Everybody’s favorite wonder material, graphene, continues to surprise. MIT physicists have discovered yet another brand new electronic state hiding in this overachieving little material – something they give the bizarre name of “ferro-valleytricity.”
