A. At the magnetic pole of earth; angle of dip is 90° and BH = 0.
B. At the magnetic pole of earth; angle of dip is zero and Bv = 0.
C. At the magnetic equator of the earth; angle of dip is 90° and BH = 0.
D. At the magnetic equator of the earth; angle of dip is zero and Bv = 0.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
At magnetic equator of Earth, the magnetic field lines become parallel to surface of earth.
∴ Angle of dip = 0°
and BH = Bnet, BV = 0
At magnetic, poles of earth, the magnetic field lines become perpendicular to surface of earth
∴ Angle of dip = 90°
and BH = 0, BV = Bnet
