Magnetism and Matter

Current loop as a magnetic dipole and its magnetic dipole moment, magnetic dipole moment of
a revolving electron, magnetic field intensity due to a magnetic dipole (bar magnet) along its
axis and perpendicular to its axis, torque on a magnetic dipole (bar magnet) in a uniform
magnetic field; bar magnet as an equivalent solenoid, magnetic field lines; earth’s magnetic
field and magnetic elements.
Para-, dia- and ferro – magnetic substances, with examples. Electromagnets and factors
affecting their strengths, permanent magnets.

Current Loop as a Magnetic Dipole

Magnetic dipole: An arrangement of two equal and opposite magnetic poles separated by a small distance is called a magnetic dipole. Magnetic dipole moment: The magnetic dipole...
