Magnetic Effects of Current and Magnetism

Chapter–4: Moving Charges and Magnetism Concept of magnetic field, Oersted's experiment. Biot - Savart law and its application to find the magnetic field near a current carrying circular loop. Ampere's law and its applications to to find the magnetic field near an infinitely long straight wire carrying current. Straight solenoid (only 11 qualitative treatment). Force on a moving charge in uniform magnetic and electric fields. Force on a current-carrying conductor in a uniform magnetic field, force between two parallel current-carrying conductors: definition of ampere. Torque experienced by a current loop in uniform magnetic field; Current loop as a magnetic dipole and its magnetic dipole moment. Moving coil galvanometer: its current sensitivity and conversion to ammeter and voltmeter.

Chapter–5: Magnetism and Matter Bar magnet:

bar magnet as an equivalent solenoid (qualitative treatment only), magnetic field intensity due to a magnetic dipole (bar magnet) along its axis and perpendicular to its axis (qualitative treatment only), torque on a magnetic dipole (bar magnet) in a uniform magnetic field (qualitative treatment only), magnetic field lines. Magnetic properties of materials- dia- para- and ferro - magnetic materials with examples, Magnetization of materials, effect of temperature on magnetic properties
