High Rez EMF Mapping: Seeking Advice

[veld]

Greetings, This was posted in the Classic Physics section, reposted here in Quantum section in case someone here may have some experience in EMF mapping.

I am currently working on an interesting experiment on crystalized metal and I need to find a way to get a detailed map of an electromagnetic field when DC current is induced into a metal sample. I found the basic 2D approach of using conductivity paper and Ag ink to be useless as it produces very crude results. I am looking for a way to yield more detail with fine lines that will show greater characteristics from my sample. A 3D map would be a good start I would think. I also would think such a fine mapping would be sensitive to environmental fields such as the Earths magnetic field, so I am guessing the experiment will need to be shielded in some way. My objective is to be able to differentiate between a crystalized and non crystalized sample based on its EMF signature, that is if its possible.

Does anyone know of a way EMF's are mapped more precisely 2D or 3D? Sorry I am not a physicist so I am not familiar what is used in this type of work. Thanks in advance for any suggestions.

Hello, it sounds like you are working on a fascinating experiment! I am not an expert in EMF mapping, but I do have some suggestions that may be helpful.

First, have you considered using a magnetic field probe? These probes are designed specifically for mapping magnetic fields and can provide more detailed and accurate results compared to using conductivity paper and ink. They can also be used in 2D and 3D mapping.

Additionally, if you are concerned about environmental fields interfering with your results, you can use a Faraday cage to shield your experiment. This will help to minimize any external electromagnetic interference.

Another option is to use a computer program to model and simulate the EMF field. This can provide a more precise and detailed map of the field without the need for physical mapping.

I hope these suggestions are helpful. Best of luck with your experiment!
