Creating Magnetic Field Project: Measuring Intensity

AI Thread Summary
Creating a magnetic field can be achieved using an electromagnet, which can often be found in devices like electric pencil sharpeners. By disassembling the sharpener and removing the grinding components, a sufficient magnetic field can be generated to observe effects on plants. Caution is advised when working with AC voltage. To measure the intensity of the magnetic field, gaussmeters are recommended, with resources provided for purchasing and understanding their use. The specific effects of magnetic fields on plants remain uncertain, indicating a need for further exploration in this area.

How would one create a magnetic field?

If a science fair project I want to observe the effects of a magnetic field on plants. Is this a good idea?
How would one measure the intensity of the field?

Well, basicly you need an electro magnet to generate a field.

You can find a pretty decent one inside of an electric pencil sharpener.

These use an ac voltage though so be carefull. Most of the time you can just open the case, remove the grinder and drive parts, and this will create a nice field. Atleast good enough to effect a plant or two.

As to measuring the intensity of the field, uhhh, brainfart,

Here is a place that sells them if you want a nice touch.

that might help. And I'm sure someone on here can explain it.

As to what effects it will have on a plant, I dunno.
 

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...
