Engineering Handbook/ElectroMagnetic

Electric Magnet Any current conducting conductor has: Magnetic poles: The north pole corresponds to positive polarity and the south pole corresponds to negative polarity A magnetic field consisting of field lines running from north pole to south pole Magnetic Field 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 Electromagnetism 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 . - epsilon =
