A new Magnetometer developed
- Scientists from RRI Bengaluru have developed a magnetometer for a more efficient, faster, and low-cost digital receiver system that can make precise measurements of magnetic fields.
- The system costs less than 350 $ for all the silicon-based hardware and associated software.
- A magnetometer is a device that measures magnetic field or magnetic dipole moment.
- The hardware of digital receiver systems are built with standard silicon-based memory devices.
- Computer codes are implemented that make these devices perform mathematical operations on the signal they receive, enabling DRS systems to measure fundamental properties of matter like ‘Spin’.
- The spin of electrons determines the magnetism of most of the objects around us.
- These spin fluctuations cause what scientists call ‘spin-noise’.
- By measuring the tiny fluctuations in the magnetic field, the researchers can infer the spin-noise accurately.
