NEET Physics Earth's Magnetism MCQ Question
Which of the following statements about Earth's magnetism is correct?
The angle of dip is the angle that the total magnetic field makes with the horizontal surface of the Earth.
The magnetic declination is always equal to the angle of dip at any location.
A magnetic needle balanced in the magnetic meridian will show a dip angle of 90° at the equator.
The horizontal component of Earth's magnetic field can be determined from the angle of dip and total field strength.
Correct Answer
Detailed Explanation
The angle of dip, also known as inclination, is defined as the angle that the total magnetic field of the Earth makes with the surface of the Earth. The other statements reflect misconceptions regarding the relationship between declination, dip angle, and the behavior of magnetic needles.
