Question

The horizontal component of the Earth's magnetic field is 3.6 × 10 - 5 T where the dip angle is 60 ° . The magnitude of the Earth's magnetic field is, 2.8 × 10 - 4 t e s l a, 2.1 × 10 - 4 t e s l a, 7.2 × 10 - 5 t e s l a, 3.6 × 10 - 5 t e s l a

MARKS App · Accepted Answer

Horizontal component of Earth’s field, H = B cos θ , since, θ = 60 ° 3.6 × 10 − 5 = B × 1 2 ⇒ B = 7.2 × 10 − 5 tesla
