Electric Magnet

[edit | edit source]

Any current conducting conductor has:

  1. Magnetic poles: The north pole corresponds to positive polarity and the south pole corresponds to negative polarity
  2. A magnetic field consisting of field lines running from north pole to south pole

Magnetic Field

[edit | edit source]

1) For a straight line conductor connects to Positive voltage . The Magnetic Field consists of Circular Field Lines counter-clockwise

2) For a straight line conductor connects to negative voltage . The Magnetic Field consists of Circular Field Lines clockwise

3) For a Coil constructed from straight wire with several turns . The Magnetic Field consists of elliptical Field Lines that has

For a Coil constructed from straight wire with several turns . Then

  • Magnetic Field Strength
B = L I
  • Magnetic Flux on the turns
  • Magnetic Force .
F = B l
  • Voltage Induced on the Coil .
  • Voltage Induced on the Turns .
