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 ...

The magnet floating device operates using a small Hall Effect sensor where the field of the permanent magnet can be detected or be able to modulate the magnetic field of electromagnet. The magnet ...

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 ...

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 ...

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 ...

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 ...
