  1. 12.4 Interaction between Electric Currents and Magnetic Fields

  2. Single Charge • Produces a magnetic field

  3. Current of Charges • Produces a magnetic field

  4. Compasses around the wire can help you detect the field.

  5. More loops in a wire • the stronger the magnetic field

  6. Electromagnet • Iron surrounded by a current carrying wire

  7. Uses • Separating scrap metal

  8. CERN • European Center for Nuclear Research

  9. CERN • Geneva, Switzerland

  10. Barrell Toroid

  11. Barrell Toroid • Atlas Detector – particle detector at CERN • Goals of Atlas • Why do particles have mass? • What makes up 96% of the universe? • Why does the universe prefer dark mater?

  12. Altas

  13. Altas used to find Higgs Boson • Particle is believed to gives particles mass

  14. Uses for Superconducting Magnets • Trains

  15. Uses for Superconducting Magnets • MRI • Magnetic resonance imaging
