NEET-Level Practice: Magnetism and Matter

A focused NEET-pattern practice quiz on Magnetism and Matter — properties of field lines, Gauss's law, bar magnet as a solenoid, torque and energy of a dipole, the B-H-M-χ\chi-μr\mu_r relations, and the dia/para/ferro classification with the standard examples. Single-concept speed is the goal: read, recall the key line, mark, move.
