MCQ
The correct relation is (Where $B_H=$ Horizontal component of earth's magnetic field; $B_V=$ Vertical component of earth's magnetic field and $B=$ Total intensity of earth's magnetic field)
  • A
    $\boldsymbol{B}=\frac{B_V}{B_H}$
  • B
    $\boldsymbol{B}=B_V \times B_H$
  • ✓
    $|\boldsymbol{B}|=\sqrt{B_H^2+B_V^2}$
  • D
