The earth's Field is Roughly equivalent to an axial centered dipole. Find the vertical rate of change of the vertical component of the earth's field in gammas/foot here at flagstaff. Given" vertical component of earth's magnetic field at flagstaff is equal to 0.6 Oesteds.

To find the vertical rate of change of the vertical component of the Earth's field at Flagstaff, we'll use the given information about the vertical component of Earth's magnetic field at Flagstaff.

The vertical rate of change of the vertical component of the Earth's field can be calculated using the formula:

Rate of change = ΔB/Δh

Where:
ΔB is the change in the vertical component of Earth's magnetic field
Δh is the change in height

To use this formula, we need to convert the given magnetic field measurement from Oersteds to the appropriate unit, which is gammas per foot.

1 Oersted = 1,000 gammas
1 foot = 30.48 centimeters (cm)

Now, let's calculate the rate of change:

Given:
Vertical component of Earth's magnetic field at Flagstaff = 0.6 Oersteds
1 Oersted = 1,000 gammas

So, the vertical component of Earth's magnetic field at Flagstaff in gammas is:
0.6 Oersteds * 1,000 gammas/Oersted = 600 gammas

Now, we can calculate the rate of change using the formula:

Rate of change = ΔB/Δh

Since we are given only the initial vertical component of Earth's magnetic field at Flagstaff and not the change in height, we won't be able to calculate the rate of change without additional information.
