Question

The magnitude of earth magnetic field at magnetic equator is 2.8 × 10^-5 T. Find magnitude of earth's magnetic field near geomagnetic poles.

Answer 1

Hello dear,

● Magnetic field-

It is a vector field that describes the magnetic influence of electrical currents and magnetized materials.

● Answer-

Bp = 6.8×10^-5 T

● Explaination-

# Given-

Beq = 3.4×10^-5 T

# Solution-

Magnetic field at poles is twice to that at equator.

Bp = 2 Beq

Bp = 2 × 3.4×10^-5

Bp = 6.8×10^-5 T

Therefore, value of magnetic field at equator is 6.8×10^-5 T.

Hope it helps...
