Lecture No. 6

  • Applications of Biot-Savart Law
  • Manetic field due to a circular current loop
  • Special cases (at centre/at large distance)
  • Tiny current loops are magnetic dipoles
  • Magnetic field lines of a tiny current loop
  • Magnetic field at the axis of magnetic dipole
  • Magnetic field of magnetic dipole on its axis vs Electric field of electric dipole on its axis
  • Magnetic torque vs Electric torque
  • Magnetic energy vs Electric energy
