Magnet Myths and Misconceptions

No, power us a measure how quickly energy is transferred.

Brad, verpies is correct.

Power is Joules per second, or J/s.

Now when you multiply power by time (i.e. seconds) to obtain the energy E, the seconds cancel and you are left with Joules (J).

Power, on the other hand, is a measure of how much we CAN produce. It is not a measure of how much energy there actually is, but a way of describing how much could be produced.

Quote: What is a kilowatt hour? As a unit of measurment, it is actually the same thing as a joule, it is just a way of measuring energy.
It is very hard to use terms and measurements you guys like,when what we are being told is different depending on who is telling us.

. That alone is a differential in itself.
The short can occur many times during induction.
Steel deadens the effect.

The cap does charge , the magnetic field does not have to change polarity it just has to change in its' strength

And that is why i said a changing magnetic field,and not fields.

Shorting a coil just for an instant causes a spike which can be collected.

If your collecting the inductive kickback,then you are not shorting the coil.The spike is created when the coil's current input is interupted-disconected. The inductive kickback can be collected,but will not equal the input that created it-->well thats what they say anyway.

The question being asked is-was all the energy transformed from one form to another?

That's not actually how the question read.

So all that had to be done was take the power avaliable that i gave you,and use that to determond if we produced the same amount of energy from that power as we produced in the form of heat,and stored in the form of the gas.

And it is impossible to answer that question literally without a given amount of time the power source was turned ON.

If you were simply looking for an answer to question if the total energy in your system is conserved, then the numbers presented in the diagram are irrelevant and no computation is required. But I am curious to see how you yourself would take that 60W source and determine the answer to your question.

And this is a clasic example.
The question being asked is-was all the energy transformed from one form to another?
Do we get out what we put in.
We already know the answer is yes,regardless of time and power to energy conversions,and the need for endless debate on what's what,and how things should be presented.
The facts are-we have an input,and an output and a storage.
All the outputs and storage have to equal the input,regardless of what the inputs and outputs are-->unless you have discovered a way to destroy energy-->this is your own beloved physics.
What go's in ,must come out or be stored.

Power can be converted into energy.Power is a measure of how much we CAN produce. It is not a measure of how much energy there actually is, but a way of describing how much could be produced.

Actually it isn't.  Power is the time derivative of energy.  It is the rate at which energy is transferred.

So all that had to be done was take the power avaliable that i gave you,and use that to determond if we produced the same amount of energy from that power as we produced in the form of heat,and stored in the form of the gas.

What you seem to be missing is that you just as one cannot read their current speed from their automobile's speedometer and determine distance, one cannot use power without integrating it over time to determine energy.  In the special case where power is constant, the integral is just that constant power level multiplied by the time interval that the power is applied.  In all other cases it is more complicated.

But what happened insted was a full refit of the space shuttles computing system--> and MH wonders why there is a 100 pages of !go no where! babble.

You may well feel that you have an idea clearly worked out in your head.  When you attempt to express that idea using ambiguous or even self-contradictory language, the chances that you will successfully convey that idea are poor.
