Tough tough question: Calculating magnetic Flux in water

AI Thread Summary
Calculating the change in magnetic flux produced by a spinning 1.61 tesla magnet in water involves understanding the geometry of the setup, including the dimensions of the vortex created. The magnet is centered in a 19-inch tall, 13.5-inch diameter container, spinning at 350 RPM with a propeller generating a vortex that narrows from 6 inches to 4 inches in diameter. The water's relative magnetic permeability is 1, indicating it does not affect the magnetic flux or field. To determine the induced EMF, one must analyze the magnetic field changes as the vortex interacts with the magnet. Accurate calculations will depend on the specific parameters of the magnetic field and the dynamics of the vortex.

Hey all, so i have a cylindrical 1.61 tesla magnet with pole orientations (+)_)- being spun at 350RPMs in a cylindrical body of water. The body of water dimensions are 19inches tall, and 13.5 diameter. The magnet is centered in the container of water.
Also, the magnet is spinning with a propeller on the top of it so it is generating a vortex. the vortex is approximately 6inches in diameter at the surface of the water, and at the point it reaches the magnet it is about 4inches in diameter. I am really trying to determine the change in magnetic flux that way i can determine how much EMF is being produced. :redface: So, if anyone can help me it would be really appreciated.

It doesn't matter whether the water is moving or stationary. Water has relative magnetic permeability = 1 so it has no effect on magnetic flux or field.
 

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...
