Imagine a quadcopter hovering above a payload – a can of beans, perhaps. The ‘copter descends onto the payload, activates an electromagnet, and flies away with a hobo’s dinner. Right now, this is a ...
Magnets are awesome. Electromagnets are even cooler. But what if you could make a semi-permanent switchable magnet that acts like an electromagnet, but doesn’t use any energy to hold metal? You’re ...
Storch Magnetics has developed a magnetic sweeper that can be equipped with a permanent magnet or an electromagnet for vehicle-mounted applications such as a forklift ...
Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...
Magnets like this one are great at picking up metal objects like these, but once you pick them up how do you let them go? For that you need a special type of magnet – an electromagnet. Magnetism and ...
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 ...
A researcher in New Jersey says he had a nuclear fusion breakthrough while helping his son with a science project. He realized he could explore which kinds of permanent magnets could be powerful and ...
