In the magnetic meridian of a certain place, the horizontal component of the Earth's magnetic field is 0.26 units and the angle of dip is 60°. What is the magnetic field of the Earth at this location?

Physics

Answer: A. 0.52 units

With horizontal component H = 0.26 and dip 60°, the Earth's field B = H / cos 60° = 0.26 / 0.5 = 0.52 units.
