Question

vi) A place where the horizontal component
of Earth's magnetic field is zero lies at
(A) geographic equator
(B) geomagnetic equator
(C) one of the geographic poles
(D) one of the geomagnetic poles​

Answer 1

the answer was not in the option . the answer is North georaphic poles

Answer 2

North magnetic dipole is the dipole that is located in Canada and it has zero dipole.

None of the option is correct.

Explanation:

• The magnetic field of earth extends from interior part of the earth towards the space. This magnetic filed is also known as geomagnetic field.
• Electric current produce magnetic filed.
• The electric currents are generated by the convention currents which emerge from the outer core of the earth.
• Heat escapes from the core and produces convention currents.
• North magnetic dipole is the dipole that is located in Canada and it has zero dipole.
