Well , I should probably take my own advice and read the book before I seem to be promoting it which I am not.
I am promoting the idea of critical and intelligent review.That all
And no , I don't have time or inclination just to bait all of you into a time wasting excercise. While I am...
I will pay 40 bucks of my hard earned for a fresh idea. I will pay you 40 bucks if you can come up with a fresh idea.
I am amazed at the emotional energy level here. The definition of a sucker is someone who thinks there going to get something for nothing and ends up paying for it.
This...
Nice try boys .
So no one has read the book. I have it on order myself , I will let you know.
Maybe others will recall that the light passing through substance issue ( how it retains momentum) was discussed in depth in this forum and there was an amazingly high degree of disagreement...
Which of you has read the book?
Its only 40 bucks , roughly the cost of a movie for 2.
I will pay one of you the $40 to read it and write a full review in this site
Or are you folks just sooo busy you have to prejudge everything through the lense of your own formal and highly...
Very interesting , I sure hope someone replies
Also , if the Earth's core is iron , and it is rotating inside the Earth's magnetic field , why isn't EMF created and where does it go if it is?
I suppose the lines of force may be rotating also so there is no work done with respect to the...
In the novel Atlas Shrugged , John Galt invented a motor that ran on the electric charge in the atmosphere , I suppose a kind of static electricity accumulator.
Lightning occurs when this static charge concentrates in clouds and a diiference in potential exists between the cloud and the...
This is very interesting , and I am grateful to all who have posted replies and explanations to me.
It is important for someone to know their limitations , and the truth is I expect I do not have the math to comprhend fully some of what has been said , and quite likely the most important...
My thanks to both Gokul and Modey. It starts to become more clear.I do agree that the magnetic field is strongest when the alignment is perfect. I also concede enthusiastically that the process of demagnetization is thermal energy , and this makes sense becasue I know that magnetic substances...
Ah hah
So its like if a rocket engine were exerting a force against the direction of motion of an asteroid, but every nanosecond changing its own angle of attack to exactly be equal to the infinitely small change in the direection of the asteroid accomplished by the thrust in the previous...
Modey
many thanks for your post.
You are saying the magnet does not expend energy to stick to the fridge.The magnet received energy to align the spins of the material.
The atoms of the magnet once imparted with this spin will keep it forever in the absence of thermal or other random...

According to my interpretation of thsi in my diagram the lectron moves toward the upper left of the screen. Agree
Lorentz force

In physics, the Lorentz force is the force exerted on a charged particle in an...
I understand the idea behind the force equation , I thank you for reposting it for me.
An electron is moving from right to left on this screen

The mganetic Loerentz force direction is from bottom to top of this screen...
Sorry , I was attempting to have you explain what the nature of the interaction is between the electron and the magnetic field that will cause the electrons path to change.
I assume I can get the answer by learning what a " magnetic Lorentz force is and how it works on particles with or...
Thanks again
Hmmm. Would you say that if the direction of a particle with mass is altered by a magnetic field that no work has been done ?
In a way I have failed to make my question clear becasue you have not answered it . Why does the magnet fall off in time , and why doesn't any old...
Thank you Zapperz
I think I undertsand the work function. If nothing moves no energy has been expended.
But the force of gravity is pulling me to the floor all the time. If I don't sit in a chair but stick my rear out as if I was I am certain I am expending energy to keep from falling to...
