AI Thread Summary
Exposure to a 22 kVA magnetic field from a reactor may not pose significant health risks, as similar high magnetic fields in medical applications like MRI imaging have shown no adverse effects. The strength of the magnetic field is not solely determined by the kVA rating, and factors like core material (iron vs. air) influence magnetic flux behavior. Personal experiences indicate minimal effects, such as display distortion on CRT oscilloscopes, when working near large air core inductors. Overall, while there can be minor interactions with electronic devices, significant health impacts from such magnetic fields are unlikely. Understanding the specific context and conditions of exposure is crucial for assessing safety.

What would happen if a person come across magnetic field produced 22 kva reactor.? I thought probably nothing will happen. Is it correct or not?? If Yes, Will you have any supportive ans for my question?
 
Engineering news on Phys.org
The KVA of the reactor does not really define the magnetic field strength. However there are application when people are routinely exposed to VERY high magnetic fields (MRI Imaging is a good example) and no adverse effects.

I did have my credit card magnetic strips erased - they were in my wallet - and I am completely nor..., wait bad example.
 
If it's iron core the magnetic flux stays almost completely in the iron.
Air core , well it spreads out into surrounding volume.
I worked next to a huge air core inductor for hours. The only effect I noticed is it rotated the display on my CRT oscilloscope.
I can't remember the exact flux - but places in that power plant I could measure 2 volts AC 60 hz with my "Flux Detector", which was just a ten turn coil with area 1/10 square meter . Flux is easy enough to calculate from that.
Next time i'd make it 1/3.77 square meters (or 1/pi for 50 hz).

Was that the scope at home after work? :biggrin:
 
The 'scope recovered as soon as it was out of the area.

But - hmmm ... it wasn't long after that I met my wife, Fair Anne . She said I seemed somehow magnetic...

:smile: You do have a magnetic personality. And I like it too. :approve:
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
