Faraday paradox revisited,magnetic field rotation question.

[guest1289]

    The  Rotating-Permanent-Magnet  in the  Faraday-Magnetic-Rotation  experiment below( on wikipedia ),  not only  rotates  around the  electrical-conductor,    it  also  rotates  on it's  'own-axis'.

     However,  everyone says that you can't make a  disk-magnet spin using electric-current ?

     I assume this contravenes the  Farday-Paradox( not sure ) .

First one is about issues with earths field affecting magnets as we simply play with them on a table. Tried it at home, work and my shop.  Earths field is pretty strong and should be considered in certain magnet motor setups. Maybe it can be used. The poles are sooo far away. Not like Things we spin on the bench where there is very close proximity with high lenz drag and cogging(cores). Here we have the same strength of field from the earth, within say a bench top device.

The mags spinning on a spindle on the outer edge of the rotor doesnt apply drag to the system, other than keeping itself in an earth field alighment, depending on the rotor alignment.

What is very interesting here is, you can compare a magnets field, at a certain distance from another mag, one on each facing side of the test mag, enough to neutralize the earths effect on the test mag. So say I have the test mag set up so it is just naturally pointing N as shown in the vid. Now from the N side and S side of the test mag, slowly bring closer similar mags with their face in repulsion of the test mag to a point where you can easily turn the test mag away from the earths pole.  That would be a test to see how the mag react to each other vs their earth compass function. Once they are at a distance from one another, then they can be used as switching devices without any drag affects on the rotor. The only physical effect of the edge mag on a spindle is to keep in pole alignment, of which you can do work for the price of getting the rotor with total rotor weight up to speed. The mags will follow earths fields pretty strongly if u use the right mags.

The second vid is of things you are discussing.

Soo. Can we apply dc at one edge of the disk magnet(on and axle) an the other dc lead to the other edge of the magnet. Will it spin? Will it be the magnets own functions and reactions to itself that makes it spin, or is it the field of the input wires that get it going?

Nowhere in any of the articles I have seen does it mention the magnet rotating on it's own axis. In fact this experiment proves nothing more than conventional motor theory and gives no indication as to whether the permanent magnet field rotates or not. You do understand the conductor has a circular spin field which falls in line with basic motor theory don't you?.

Place a metal magnet in water add a charge and it will spin ! You don't understand  anything outside the book of deadheads and rotten broomsticks ..................... Don't insult or you will be made to look like an idiot ... !

That is quite a vague statement.
Add a charge?
Are you thinking like a static charge or ..... some current flow from point A to B or some type of yet unknown principal?
You might want to be more specific so you don't insult yourself.

   This post is about the  permanent-magnet   orbiting around  an  electrical-conductor  in the  Faraday-Motor  below  :

    Nowhere in any of the articles I have seen does it mention the magnet rotating on it's own axis.

    I should have typed  'magnet rotating on it's own axis from the perspective of the  current-carrying-wire,  around which the magnet is orbiting.
     
    Pretending my mouse is the  permanent-magnet  orbiting in this motor,  if I swing my mouse by the cord around an object,  in 1 orbit,  the magnet has also done 1-full rotation on it's own axis,   from the perspective of the  current-carrying-wire .

    -  What if the magnet was prevented from orbiting around the wire,   and you added a  shaft  to that  magnet  to permit  the magnet  to rotate on it's own axis,   I just assume that the magnet  should  then  'rotate on it's own axis' ,   from the perspective of the earth.
        -  But everyone says it will not rotate.

    -   What if the only change you made to the motor,  was to simply add a shaft  to the  magnet  to permit  the magnet  to rotate on it's own axis,   and you still allow the magnet to  rotate/orbit  around the wire,   I wonder what would happen .

    -  If no liquid is utilized  in this motor,  by using brushes for example,  I assume that that  magnet  will still  orbit  around the  wire,   but I don't know,  surely it has nothing to do with the  liquid-mercury( or brine substitute ) .
        I have never seen any other  motor  where a  symmetrical-magnet  like this one ,  orbits,  or rotates on it's own axis from the perspective of the  current-carrying-wire .

In fact this experiment proves nothing more than conventional motor theory and gives no indication as to whether the permanent magnet field rotates or not. You do understand the conductor has a circular spin field which falls in line with basic motor theory don't you?.

   Yes,  all of the  electric-motor-deigns  I have posted on this site,  are designed to  function  'directly'  from the interaction with that   'circular spin field'.

    You can get a disc magnet to spin either in water or on a crystal lenz or in a DJ turntable drive or by inductive resonance or in zero gravity

 

you can get it to spin X potentially if you coat it in silver then varnish and hit it with a lot of volts or static or monopole pulse

   This could give me a clue as to what else could be going on in that motor,  if in fact this motor is different to other normal motors,   although these days they substitute the mercury with brine,  but you have also mentioned  water .
