• Magnetic field


  Represented by B symbol
• Magnetic field


  SI unit is Tesla (T)
• Magnetic force


  Attraction or repulsion that arises between electrically charged particles because of their motion
• Right Hand Rule


  • Useful mnemonic for visualizing the direction of a magnetic force
  • thumb - velocity of the charge (v)
  • middle finger - the magnetic force
  • pointing finger - the magnetic field
• Magnetic flux (φ)


  The number of magnetic field lines passing through a given closed surface
• Magnetic flux (φ)


  Provides the measurement of the total magnetic field that passes through a given surface area
• Weber (Wb)


  SI unit of magnetic flux
• Magnetic flux


  Represented by the Greek letter Phi (φ)
• Magnetic flux density (B)


  The force acting per unit current per unit length on a wire placed at right angles to the magnetic field
• Magnetic flux density


  Same SI unit and symbol to magnetic field (B) and (T)
