Question

The total magnetic field of earth is 3.2a/m then the magnetic inductin

Answer 1

B=μH

B=

$= 4\pi \times {10}^{ - 7} \times 3.2 = 4 \times {10}^{ - 6}$

Answer 2

Given,

Magnetic field (H) = 3.2 A/M

To find,

The magnetic field of the Earth (B)

Solution,

We know, that relation between Magnetic field and Magnetic induction is given by,

B= μ × H,

The default value of μ is 4π × $10^{-7}$,

B = 4 × 3.14 × $10^{-7}$ × 3.2 ,

B = 4.0192 × $10^{-6}$ Tesla.
