Earth's Magnetic Field: Vertical Direction

AI Thread Summary
The vertical component of the Earth's magnetic field does not always point downward, particularly at the equator where it is horizontal. At points of the same latitude on opposite sides of the equator, the vertical components differ; one points upward while the other points downward. This variation occurs due to the definition of upward and downward based on the horizontal direction. Understanding these differences is crucial for accurate navigation and geophysical studies. The Earth's magnetic field exhibits complex behavior that varies with geographic location.

Does the vertical component of the Earth's magnetic field always point downward?
 
Physics news on Phys.org
Hi.

There is horizontal and no vertical component on equator.

Thinking of two points of the same latitude but on opposite sides the equator, the vertical components are upward at one and downward at the other when we keep the same horizontal direction in definition of upward and downward.

Regards.

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
