  2. What is FMCG?

  3. Magnetic sensors

  4. Magnetic sensors & biomagnetic signals

  5. Bio-magnetic signals 1T= 10 000 Gauss

  6. What is a SQUID? Is this the Squid we want to use?

  7. What is a SQUID? The SQUID we want to use ! • Superconducting QUantum Interference Device • at 77K (LN2) • superconductivity -196°C

  8. Features of Superconductivity • Zero Electrical Resistance • Meissner Effect • Magnetic Flux Quantization • Josephson Effect
