Magnetic Wankle Motor

[babieintown]

Hi guys
I come to this forum so late
and found out i cannot understand all of the threads.

I'm interested in the magnetic wankle motor. But when i search on it
i found that there is a rotary wankle motor too.
Are these two thing related in anyway?

Besides i read the old threads in the forum, and found some said about the energy to make magnets are 10-20 times the overall energy that magnets can give in their life before they demagnetized. So i wonder, is there anyway to keep magnet magnetized forever so we can harvest the energy from them until we get back the energy that used to make the magnets and reach the real OU after that point?

1) The Rotary Wankel and the Magnetic Wankel have nothing in common except the name.
2) Magnets don't get demagnetized when being operated in attraction mode so this is the least of your worries.

Hi Ergo

Could you give me some resources that explain about preventing magnet from demagnetized by operating in attraction mode
and is it possible to to keep imagnet magnetized forever? if yes, how should we  take care of our magnets.

I'm still little paranoid...before i invest some of my money 
Hope you understand

Babieintown, I have read a few of your post and like most of us it seems you have a lot of questions and have a lot to learn. I have a feeling you have a lot of reading to do. Here is a link to a great site that explains magnets and magnetism. I think it will answer a lot of your questions. Read it all! I did several times when I first started looking into this stuff.

I think you will find that neo or most permanent magnets don't actually loose their magnetism, but they become internally aligned magnetically, forming a closed magnetic loop within the magnet itself by physical shock (striking the magnet), or heat or a repulsively strong enough magnetic field (with velocity) to overcome the strength of the pinning material in the magnet.  The "pinning material" that holds the magnetic particles in place looses it's grip on the magnetically aligned order of the particles and they then seek to align themselves with the closest, strongest source, which is each other within the magnet.  This forms a closed magnetic loop which emits no magnetic field externally, so the magnet appears to have 'demagnetized'.  If this happens to only part of the magnet, the magnet is only weakened since only some of the particles have realigned internally and others stayed aligned with an external focus (original magnetic alignment).  So the particles don't actually demagnetize, but become realigned in an undesired direction.
