This activity is part of the Science Friday Sun Camp collection! The Sun generates an incredible amount of energy, energy that you can see and feel as light and heat. Other forms of energy from the ...

Scientists have made a breakthrough in the search for a new, sustainable permanent magnet. Scientists have made a breakthrough in the search for a new, sustainable permanent magnet. Most permanent ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

Warnings about magnets and gadgets have been passed down like tech folklore, often without much explanation. The reality is more nuanced: some electronics are genuinely vulnerable to magnetic fields, ...

Permanent magnets play a crucial role in medicine due to its field strength, tunability of field and gradient distributions, as well as practical implementation. In a new study published in KeAi ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...

Japanese manufacturers are developing technologies to make powerful motor magnets used in electric and hybrid vehicles without utilizing geopolitically sensitive heavy rare earths that are largely ...

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...

China’s exports of permanent magnets rose to a six-month high in July, marking a second month of growth after the government pledged to accelerate export permit approvals for the rare earth derivative ...

Protect the supply lines. This is a fundamental military tenet. Cut the supply lines and an adversary is weakened, vulnerable, paralyzed. This rudimentary principle also applies to our current high ...
