Discussion Overview

The discussion revolves around the effects of a primary coil placed at a 90-degree angle to a secondary coil in a transformer setup. Participants explore the implications of this configuration on induced current and voltage, as well as the behavior of electrons in the secondary coil. The conversation includes experimental observations and seeks to understand the underlying physics of the phenomena observed.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant describes a setup where a primary coil is pulsed at a 90-degree angle to a secondary coil, questioning how this affects induced current and voltage.
  • Another participant expresses frustration over the lack of clear explanations regarding the effects of flipping the magnetic flux 90 degrees.
  • A suggestion is made to provide pictures of the experimental setup and oscilloscope patterns for better understanding.
  • A participant notes that current through a coil produces magnetic flux at a right angle to the coil and discusses the role of a laminated iron core in traditional transformers.
  • Further details are provided about the experimental results, including observations of small waveforms off-load and larger waveforms under load, as well as voltage readings with a full wave bridge rectifier.
  • One participant speculates on the effects of magnetic flux on copper atoms in the secondary wire and questions the complexity of the inquiry.
  • Another participant suggests that the horizontal wire may develop magnetic polarity during each pulse, which would dissipate after the pulse ends.

Areas of Agreement / Disagreement

The discussion reflects multiple competing views and remains unresolved, with participants expressing differing interpretations of the experimental results and the underlying physics. There is no consensus on the effects of the 90-degree configuration on induced voltage and current.

Contextual Notes

Participants note various experimental observations, including the behavior of waveforms under different loading conditions and the potential implications for applications in chemistry. However, the discussion does not resolve the underlying assumptions or the complexities involved in the transformer design being investigated.

Here is a reworked question...

If i have a secondary coil and pulse a primary that is placed 90 degrees to the secondary so the magnetic flux is at a 90 degree angle to a normal winding (secondary is wound east to west primary is north to south) then how will this effect the induced current/voltage and effect the way the electrons flow.

I have tried this but cannot explain the weird scope and meter readings.

thanks
 
Physics news on Phys.org
I think it may shed some light on things if someone with a good understanding of physics can give a reason why they cannot give a answer. All i have done is flip the magnetic flux 90 degrees, can it be that difficult nobody can explain it?

yours baffled
 
How about some pictures of your set-up and the scope patterns?
 
Disclaimer: I'm no Physicist.

As I recall, current flowing through a coil produces magnetic flux 90 degrees to the coil.
In a transformer, that 90 degrees is taken up by a laminated iron core.
The magnetic flux lines travel along the iron core until they encounter another coil. At that time, the magnetic flux re-converts 90 degrees back to electric current (or potential).

Assuming I understand what you're doing correctly, having one coil pass through another (like rings), your second coil is in an area generating magnetic flux, not voltage.
 
Thanks for the replys i shall add some more info, i do not want to over complicate things so think of this as a primary winding cutting flux at 90 degrees from the normal angle into the secondary.

Hi fester, i think you understand what i am saying the flux passes thru the wire horizontal (like rings) and not sliced thru vertical. Any idea why the magnetic flux entering the secondary would not induce a voltage, what will it do when the flux passes thru the copper wire? it must do something.

Some tests that have been done show off load only a tiny squiggle of a waveform. with a load a much larger waveform appears. For pulse input, spikes that constantly change height are observed. If a full wave bridge is added and you short the output the secondary still has voltage, say it was 12v, with the bridge + and - shorted the secondary only drops to 9v with uA current flow measured.
I have also wound more secondary coils wired in various configs to give 300+ volts shown on a scope with tiny currents measured, however it does not seem to make a real circuit, i need to understand this transformer from a physics view point.
I know people are going to think this transformer is just rubbish, but it can have a use in chemistry applying a voltage potential without current flow across a liquid. molecules being mainly made up of electrons (-) protons (+) will be affected and if you have current flow it will short out hence a new transformer design.

thanks for any input
 
A drawing of what you have would be very useful here.
 
Hi fester

A diagram (circuit and transformer) is a little off topic and only usefull if you wish to have a go at this yourself.
I suppose the best simplified diagram of what i am asking is to draw a vertical line then a horizontal line so they look like crosshairs of a gun, the vertical line is pulsed with dc and creates a magnetic flux of 1 tesla.
The question is what affect does that have on the copper atoms in the horizontal wire.

We know what happens if it is two horizontal wires, can any physics prof explain my wireing or even why this seems so far to be a tricky question?
 
Since the horizontal wire is copper, I'd say it would develop magnetic polarity during each pulse, which would end after each pulse.

As for your oscilloscope, given how sensitive those things are these days, I don't know what you'd see. It might be pretty strange though.
