A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through 181∘181^{\circ} to deflect magnet by 37∘37^{\circ} from magnetic meridian. Now this magnet is replaced by another magnet and upper end of wire has to be rotated by 273∘273^{\circ} to deflect magnet by 53∘53^{\circ} from magnetic meridian. The ratio of magnetic moment of the two magnets respectively is
View answer and explanation
Correct option: B
4855\frac{48}{55}
Option B (48/55) is correct because it is the ratio of magnetic moments calculated using the torsion constant and deflection angles.

Curie temperature is the one above which A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is 25/4{2^{5/4}}s. One of the magnets is removed and if the other magnet oscillates in the same field , then the time period in second is The relative permeability of a substance XX is slightly less than unity and that of substance YY is slightly more than unity, then A bar magnet is equivalent to If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted by μd,μp\mu_{\mathrm{d}}, \mu_{\mathrm{p}} and μf\mu_{\mathrm{f}} respectively, then :- Which of the following is most suitable for the core of electromagnets
