Earth's magnetic field always has a horizontal component except at

Options

  1. Aequator
  2. Bmagnetic poles
  3. Ca latitude of 60^
  4. Dan altitude of 60^

Correct answer

B. magnetic poles

Step-by-step solution

At poles magnetic dip, =90^ As, horizontal component of Earth's magnetic field, B_ H =B where, B is net earth's magnetic field. B_ H =B 90^ =0 So, at poles, the horizontal component of earth's magnetic field is zero.
