The actively controlled levitation base uses a magnetic sensor to detect the changing field as the snail moves above it. It then varies the current going to the various coils to keep the snail ...

They compare data from sensors with and without the reference magnetic fields applied to gauge how those sensors are responding. In most cases, those references are small metal coils, which ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to ...

Getting a magnetic field to balance ... tricky project using a set of four coils he got off of Taobao (the Chinese version of eBay), a hall effect sensor, and a handful of current regulation ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

It has the potential to revolutionize quantum sensor technology. The research demonstrates the capabilities of trapped vapor atoms. These atoms can simultaneously measure minute variations in magnetic ...
