Maybe I'm confusing myself, I'm thinking its not the magnetic field generated by the eddy currents (since that is N/S) as much as it is the expression of the Lorentz force itself as you explained: quoting Wikipedia: " It says that the electromagnetic force on a charge q is a combination of a...

Now I get it...Thank you. The leading and trailing edges of the induced eddy currents generate a magnetic field in a direction to push against the E/W motion of the metal and slow it down. Correct?

So I studied the wikipedia page referenced. An I see how up and down magnetic fields are generated from the moving metal...but please please explain how up and down forces can cause deceleration (ie. a force vector) for the E/W motion?

Thank you all for your responses...however I still don't understand. I can't imagine any magnetic field that will slow down the moving metal. Clearly the moving metal generates its own magnetic field...but how does it couple to the North/South field to slow down? The N/S field is orthogonal to...

A piece of metal moving West to East in a North to South fixed magnetic field slows down...but how? Yes of course eddy currents are set up in the metal and these currents generate their own magnetic field which somehow slows down the moving metal piece...but how does this actually slow the...

I don't understand how this resolves my original question? Please elaborate. Thanks.

I don't have this book. Please be so kind as to give a brief summary of how this relates to my question. Thanks.

I don't have access to this volume. Perhaps you could give a brief summary and explanation? Thanks.

I join as a 69 year old retired electrical engineer who is interested in physics. I have particular interest in particle physics and quantum mechanics. I don't expect to provide answers on this forum, but I do intend to ask questions.

We know that both momentum and position can not be known precisely simultaneously. The more precisely momentum is known means position is more uncertain. In fact, as I understand quantum mechanics, position probability never extends to 0% anywhere in the universe (except at infinity) for any...
