AI Thread Summary
To measure magnetic fields in a solenoid for junior students, using USB probes designed for electromagnetic experiments is recommended, as they can effectively measure weak magnetic fields. Another straightforward method involves moving a coil of wire into the solenoid from a distance and measuring the induced EMF over time, which can then be used to calculate the magnetic field strength. These approaches provide hands-on learning experiences while demonstrating fundamental electromagnetic principles. Cost considerations for the probes are mentioned, but specific prices are not provided. Engaging students with practical experiments enhances their understanding of electromagnetism.

Hi

please introduce me an electromagnetic expriment so that we can measure magnetic field in a solonoid.
I would like to use it for physics junior students.
Thank you.

When I was in my E & M class, we used probes that plugged into the USB port of a computer to measure weak magnetic fields. I have no idea how much they cost, though they seemed like they would be cheap. One other simple way to measure the field strength is to move a coil of wire into the middle of the solenoid starting from far away. Then, measure the EMF across that coil as a function of time, and use the result to calculate the magnetic 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...
