A permanent magnet ONLY "Square Drive Motor" design, UNTESTED. and an easy to build quasi test model.

The  square drive motor motor, of course does not work.  Gravitational pull is constant while the the magnetic fields decreases by
the square of the distance from the magnet's poles. The magnets will only displace each other by 10% to 15c% at  right angles.

Here is a photo and drawing of a test device, designed to crudely measure the square drive interactions. I may have misstated the magnet displacement created in the test device.  I think the attracting force magnets were displaced at around 30% by the repelling magnets.

Here is a photo(poor quality) and drawing of a test device.  Further experimentation is needed.

A permanent magnet is embedded within in an electromagnet. 

My first reaction is that, unless you are very careful, the electromagnet may tend to de-magnetise the permanent magnet.
