NCERT lines NEET asked again and again

Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

Turning a magnet from its equilibrium position costs W = mB(1 − cos θ) , while the torque holding it there is τ = mB sin θ. Link the two to get quick ratios.
AIPMT 1995AIPMT 2012NEET 2016
Pole strength stays the same, so the moment is pole strength × distance between poles . Cutting across the length halves m; bending into an arc shrinks it.
AIPMT 1997NEET 2013NEET 2024
A small-angle swing is SHM with T = 2π√(I/(mB)) . A stronger field or larger moment shortens the period; a larger moment of inertia lengthens it.
AIPMT 2003AIPMT 2010NEET 2024
A diamagnet has negative χ and μᵣ<1 , so it is weakly repelled and moves from the strong to the weak part of the field, whichever pole you bring near.
AIPMT 2003AIPMT 2009NEET 2016
The potential energy of a dipole is U = -mB cos θ, so it is lowest (-mB) at θ = 0° (stable) and highest at 180°; at 90° it is zero.
AIPMT 2011NEET 2024
Above the Curie temperature a ferromagnet loses its domain order and behaves as a paramagnet , with χ = C/(T − T_c).

Free NCERT notes for Magnetism and Matter

The bar magnet as a magnetic dipole (field lines, axial and equatorial fields, torque, energy, Gauss's law) and how dia-, para- and ferromagnetic materials respond to a field. It is a short chapter; NEET usually asks one question from it, most often on the classification of materials or the dipole formulas.

Read the chapter notes: key NCERT points, graphs, every formula with its meaning, tricks, common mistakes and NEET traps.
