Magnetism — Syllabus & Topics
Topics covered in Magnetism for NEET-UG Physics.
Topics in Magnetism
Molecular Theory of Magnetism and Bar Magnet Properties
- Every molecule of a magnetic substance is a complete magnet with north and south poles
- In unmagnetized state, molecular magnets are randomly oriented giving zero net magnetic moment
- Magnetization aligns molecular magnets in a specific direction creating net magnetic moment
Magnetic Field Terms and Quantities
- Magnetic field is the space around a magnet where its influence can be felt
- Magnetic flux (φ) is the number of field lines passing through a surface
- Magnetic flux density (B) is flux per unit area perpendicular to field direction
Magnetic Forces and Fields
- Coulomb's law for magnetism: Force between poles varies inversely with square of distance
- Magnetic field due to pole follows inverse square law like electric field
- Bar magnet creates different fields at axial and equatorial positions
Tangent Law and Tangent Galvanometer
- Tangent law applies when two perpendicular uniform magnetic fields act on a compass needle
- At equilibrium, needle aligns such that B = BH tan θ
- Tangent galvanometer measures current using tangent law principle
