12.4 Interaction between Electric Currents and Magnetic Fields
Single Charge • Produces a magnetic field
Current of Charges • Produces a magnetic field
More loops in a wire • the stronger the magnetic field
Electromagnet • Iron surrounded by a current carrying wire
Uses • Separating scrap metal
CERN • European Center for Nuclear Research
CERN • Geneva, Switzerland
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?
Altas used to find Higgs Boson • Particle is believed to gives particles mass
Uses for Superconducting Magnets • Trains
Uses for Superconducting Magnets • MRI • Magnetic resonance imaging
