AI Thread Summary
A magnetron in a microwave oven generates microwaves that heat food by causing water molecules to vibrate. The emitted microwaves are not pushed by a fan; instead, they disperse throughout the cooking chamber. This process ensures even heating of the food. Understanding the magnetron's function is crucial for grasping microwave technology. For more detailed information, refer to the provided Wikipedia link.

Hey everyone. I was wondering how a magnetron in a microwave works. I understand it emits microwaves and a fan pushes them in random directions to heat up food. Thanks.

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...
