Question

State Tangent Law in magnetism.

Answer 1

Solution:

1. Tangent Law states that when a bar magnet is left suspended in the influence of a magnetic field $\mathit{B}$ at right angle with the Earth's Magnetic Field's Horizontal Component $B_H$, it comes to rest at an angle $\theta$such that $\tan \theta =\frac{B}{B_H}$.
2. The figure above can be used to visualize the angles as well as the magnetic field components.
