TDK has demonstrated a fast optical sensor based on a magnetic tunnelling junction - a spin photo detector. he device is ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

The metal detector part of the project is fairly ... where short pulses are fired through a coil to generate a magnetic field. Once the pulse ends, the coil is used to detect the decaying field ...

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of the planets magnetic field. Data from the European Space Agency's Swarm ...

The turtles rely on Earth’s magnetic field to help them navigate in two ... When a powerful neutrino traveled through the partly finished ARCA detector off the coast of Italy, it set off sensors ...
