JEE-Level Practice Questions

JEE-Level Practice: Magnetism and Matter

A focused JEE Main / Advanced practice quiz on Magnetism and Matter — solenoid-magnet equivalence, axial/equatorial dipole fields and the $\sqrt{1+3\cos^2\theta}$ general point, torque/energy/work and oscillations of a dipole including the cut-magnet classics, Gauss's law flux counting, and the $B$-$H$-$M$-$\chi$-$\mu_r$ toolbox with superconductors. Expect multi-step reasoning; every question rewards writing the formula first.
