Topics in Electromagnetism

1

Magnetic Effect of Electric Current

  • Oersted's experiment (1820) proved that a current-carrying conductor produces a magnetic field around it
  • Magnetic field lines around a straight conductor are concentric circles perpendicular to the wire
  • Direction of magnetic field can be found using Right Hand Thumb Rule
2

Magnetic Field Due to Current in Different Conductor Shapes

  • Circular Loop: Magnetic field lines are circular near the wire, nearly straight and uniform at the center
  • Field strength increases with current and number of turns in the loop
  • Clockwise current creates south pole, anticlockwise current creates north pole
3

Electromagnets and Their Applications

  • Bar electromagnet: solenoid wound around cylindrical soft iron bar
  • Horse-shoe electromagnet: U-shaped soft iron with opposite windings on each arm
  • Electromagnets are temporary magnets that work only when current flows
4

Force on Current-Carrying Conductor in Magnetic Field

  • Current-carrying conductor in magnetic field experiences Lorentz force
  • Force is maximum when conductor is perpendicular to magnetic field
  • Force is zero when conductor is parallel to magnetic field
