To estimate the total energy stored in the field in the first 10 km above the Earth’s surface.
Answer to Problem 47P
Solution:
The total energy stored in the magnetic field is
Explanation of Solution
Given:
Average magnetic field of Earth,
Height,
Formula used:
Volume over which the field energy needs to be calculated
Calculation:
We know that the radius of the Earth,
The volume over which the field energy needs to be calculated is the volume enclosed between the two spheres of radius and .
Therefore,
Substituting the value of and
Total energy stored in the magnetic field
