What Types of Nanotechnology-Based Magnetic Field Detectors Exist?
Several types of magnetic field detectors have been developed using nanotechnology. One example is the magnetoresistive sensor, which changes its electrical resistance in response to a magnetic field. Another example is the Superconducting Quantum Interference Device (SQUID), which can detect extremely weak magnetic fields. There are also spintronic devices that exploit the intrinsic spin of electrons and their associated magnetic moment to sense magnetic fields.
