Key Topics to Revise

1

5.1 Introduction to Magnetism

  • Magnetism is derived from 'Magnesia', a Greek island where natural magnetic ore was found
  • Earth behaves as a giant magnet with magnetic field pointing from geographic south to north
  • Every magnet has two poles - North and South poles that cannot be separated
2

5.2 Bar Magnet and Magnetic Field

  • Bar magnet produces magnetic field similar to a solenoid
  • Magnetic field lines form closed continuous loops
  • Field lines never intersect each other
3

5.3 Gauss's Law for Magnetism

  • Net magnetic flux through any closed surface is always zero
  • Magnetic field lines form closed loops - no beginning or end
  • No magnetic monopoles exist in nature
4

5.4 Magnetization and Magnetic Intensity

  • When material is placed in magnetic field, it gets magnetized
  • Magnetic intensity H represents magnetizing capability of field
  • Magnetization I represents magnetic moment per unit volume
