If the earth's magnetic field has a magnitude `3.4 xx 10^(-5) T` at the magnetic equator of the earth, what would be its value at the earth's goemagnetic poles?

Explanation

To solve the problem of finding the Earth's magnetic field at the geomagnetic poles given its value at the magnetic equator, we can follow these steps:

### Step 1: Understand the Relationship Between Magnetic Field and Magnetic Moment
The magnetic field \( B \) at a distance \( r \) from a magnetic dipole is given by the formula:

\[ B = \frac{\mu_0 m}{4 \pi r^3} \]
