A earth's magnetic field at geomagnetic poles has a magnitude `6.2 xx 10^(-5) T`. Find the magnitude and the direction of the field at a point on the earth's surface where the radius makes an angle of `135^@` with the axis of the earth's assumed magnetic dipole. What is the inclination (dip) at this point?

Explanation

To solve the problem, we need to find the magnitude and direction of the Earth's magnetic field at a point where the radius makes an angle of \(135^\circ\) with the axis of the Earth's assumed magnetic dipole. Additionally, we need to determine the inclination (dip) at this point.

### Step-by-Step Solution

1. **Understanding the Magnetic Field at the Geomagnetic Poles**:
The Earth's magnetic field at the geomagnetic poles is given as:
\[
B_{\text{pole}} = 6.2 \times 10^{-5} \, \text{T}
