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

Explanation

To find the magnitude of Earth's magnetic field near the geomagnetic poles, we can use the relationship between the magnetic field at the equator and the magnetic field at the poles.

### Step-by-Step Solution:

1. **Identify the given data**:
- The magnetic field at the magnetic equator \( B_E = 2.8 \times 10^{-5} \, \text{T} \).

2. **Use the relationship between the magnetic field at the poles and the equator**:
