(i) Diamagnetic substances, when placed in a non-uniform magnetic field, tend to move from stronger region of the field to the weaker region. On the other hand, paramagnetic substances move from weaker region of the field to the stronger region.
Here B = 0.02 T, θ = 30° and t = 0.060 N m (i) ∴ Magnetic moment of the magnet m = t/Bsinθ = 0.060/0.02 × 0.5000 = 6 A m² . (ii) For stable equilibrium of the magnet ...
