Lionel Postwar 773 worm cover magnets question

I've been experimenting with my worm cover and I need someone to jump in and verify my conclusions.    Greenberg's 773 page has a "test" to determine the direction of the worm cover relative to the engine. That test assumes the magnets are mounted correctly. It says to lay the cover on a table (long sides facing away) and lower the engine perpendicular to the cover and it should spin. They then say to rotate the plate 180 and mount it with that orientation (I think they are assuming the nose of the chassis is facing right).   Here's the part I need feedback on.  I'm thinking both magnets have to have their N poles facing the same direction. I tried that by mounting the magnets with tape on the cover. N of both facing right. I lowered the engine and it spun (ended up parallel to the chassis). So...........if the nose is facing to the right, do I turn the cover so that the magnet that is facing right is now facing left and then attach to to chassis?

C.W.?    Chuck?

Well, I think on onto something here. I found the magnets in the frame and tested them. Both are aligned with their N (or S) poles facing the same direction. So......I think I was right......probably both worm cover magnets should have their N poles facing the same direction. When I did the spin test (and then rotated the cover 180 degrees), all 4 magnets were aligned with the same pole facing the same direction.   Am I correct in my thinking?' If so, I'll glue them back on and be good to go.   If not........back to square one.

That is correct - all "N" poles aligned.

Thank you, Rob. I needed that!

The magnets on the worm cover should have their poles facing the same direction.  Every time there is an interruption in the magnet, a new north/sonth pole relationship is established. So if the pole on the magnets on the cover are north, the wheel will be south by the magnets, the wheel will be north at the rail and the rail will be south, and so on until you get back to the other end of the magnets.  If there is little or no residual magnetism in the wheels, it will make no difference which way the magnets are put on.  Except if you send back to the factory to have the magnets recharged.  Then if the magnets are backwards, the recharging operation will just reverse the poles on the magnets. 

You lost me after the first sentence David.

 If there is little or no residual magnetism in the wheels, it will make no difference which way the magnets are put on.

There are also magnets mounted in the frame.
The orientation of the magnets on the worm cover must be correct for the magnetraction to work as designed.

And match the polarity of the magnets in the frame.

I've got it reassembled after the "Super Tune" I did on it (courtesy of the Just Trains website). Runs great.  So, all is well with the magnets.
