With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow.

Reading this magnetic information is complex ... from the metallic ions in its structure. When an external magnetic field is applied to these objects, the magnetic moments of each molecule are ...

Scientists have unlocked a way to read magnetic orientation at record-breaking speeds using terahertz radiation. Modern hard ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that ... verified it can at least give a believable reading derived from the Arduino’s ADC.

The magnetic field is caused by the current flowing in ... Wire gets hot Minor burns Do not handle the wire. Switch off between readings. Do not exceed a current of 1 A.

Initial experiments have already shown a promising new strategy: Magnetic states can be read ... First, the terahertz pulses, through their electric field, generate extremely short-lived electric ...
