    SQUID Magnetometer

    The superconducting quantum interference device (SQUID) consists of two superconductors separated by thin insulating layers to form two parallelJosephson junctions. The device may be configured as a magnetometer to detect incredibly smallmagnetic fields– small enough to measure the magnetic fields in living organisms. Squids have been used to measure the magnetic fields in mouse brains to test whether there might be enough magnetism to attribute their navigational ability to an internal compass. read more
