AI Thread Summary
The discussion focuses on simulating the magnetic field generated by two AC electrodes submerged in water using Ansoft Maxwell3D. The user initially attempted to set up current excitations at both ends of the electrodes but encountered issues with achieving a symmetric magnetic field. They later connected the electrodes with a copper wire and applied excitation to the wire, but the resulting J field did not indicate a strong conduction zone in the water. The user seeks guidance on the appropriate model to use—either eddy current or transient magnetic—and how to properly set the excitation for the AC electrodes. Assistance is requested to resolve these simulation challenges effectively.

Dear All,
I'd like to simulate the magnetic field produced by two AC electrodes putting into a pool (figure 1). I am using Ansoft Maxwell3D... but i don't know how to set excitation for an AC current in this case.

the first test I put two current excitations at two ends of the electrodes (with no wire connecting between them), but it won't produce a symmetric magnetic field around each electrode... (figure 2)

I draw a small wire (copper) connecting between 2 electrodes and put excitation on middle of the wire, but I don't know why the J field did not show a strong conduction zone in the water area (figure 3)

many thanks for seeing, i have solved it ok
 
Hi All,
Sorry I wish to repost this question because I still have some problems with it. Please anyone can help me: how to simulate the magnetic field produced by 2 AC electrodes putting into a pool. I have an AC power (500Hz) with 2 electrodes, then I put the 2 two electrodes in two ends of a water channel. i would like to simulate the magnetic field produced around the water channel by using Ansoft Maxwell3D, i don't know which model should i use (eddy current or transient magnetic), and how to describe and set excitation for the AC eletrodes?

Thank you very much and best regards,

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
