AC voltage from single magnetic pole

[nix85]

I think it is customary for laws to be proven, rather than disproven.

That current lags voltage by  90° in inductive circuit is as well known as Ohm's law, it's "proven" by millions of engineers every single day.

It is a law, to claim otherwise is idiocy.

It is not an idiocy. According to the scientific method every law must be falsifiable.

My stance is, that this is true only if an external voltage is applied to the inductor.

Ohm's law is a different law that does not involve pure inductors. As such, it does not have to make the distinction between two modes of energy delivery to an inductor - the magnetic one and the electric one.

... it's "proven" by millions of engineers every single day.

So would a disproof of the i&v lag in a single inductive circuit, which is NOT subjected to an externally applied voltage, be an acceptable disproof for you if it is performed by a person other than me?

Well
As mentioned before
There are Venues and persons who
Can help
Example below

Perhaps it would be good to establish a rapport
With some moderators there at physics forums or EE forums or similar elsewhere ...
To help judge such debates?

So many times here there are persons hoping to engage
The scientific perspective !




Having a venue to ask for help judging ??


Would be good for real-time debates!!

That is relative thing since all physical laws can be skewed or bypassed in certain ways, but within certain limits they hold true, see below for an example.

Your belief.

Ohm's law is a different law that does not involve pure inductors. As such, it does not have to make the distinction between two modes of energy delivery to an inductor - the magnetic one and the electric one.every law must be falsifiable

Ohm's law has it's exceptions, incandescent bulb totally ignores Ohm's law, as filament gets hotter it's resistance increases and Ohm's law is out of window, reverse happens in Neon tube with negative resistance, voltage falls with increasing current after the bulb reaches it's breakdown voltage. Etc.

So would a disproof of the i&v lag in a single inductive circuit, which is NOT subjected to an externally applied voltage, be an acceptable disproof for you if it was performed empirically by a person other than me?

Show me a near purely inductive circuit in which current does not lag voltage as magnet passes across the coil and i'll be happy to admit this law is bypassed in such case.

PS. since you will using resistive coil to prove something about ideal coils, use as thick wire as possible and at least 50 turns.

This is a tricky thing to do since you should not break the circuit. To do it right you should use two coils, one for voltage and another for current, measure current with a clamp probe for oscilloscope.

Small number of turns coil of same diameter will do for voltage.
