Examples from the Web for magnetic flux
Historical Examples
  • The total number of lines of force in the circuit is known as the magnetic flux.

  • In a radially decreasing magnetic field, the lines of magnetic flux bow outward, as represented in Fig. 4b.

    LRL Accelerators Lawrence Radiation Laboratory
  • Outside the aerial we have variations and distributions of electric strain and magnetic flux.

    Hertzian Wave Wireless Telegraphy John Ambrose Fleming
  • The intensity of a magnetic flux is expressed by the number of magnetic lines of force in a square centimeter or square inch.

  • The iron by its permeability also concentrates and increases the magnetic flux.

    Physics Willis Eugene Tower
  • He places a strong electromagnet so that its lines of magnetic flux pass transversely between the spark balls.

    Hertzian Wave Wireless Telegraphy John Ambrose Fleming
  • These lines are still called "lines of magnetic force," or by some "magnetic streamings" "magnetic flux," or simply "magnetism."
