Is output four times the input?

Magnetic field is non-physical and is flexible.  A lever is made of solid material with solid bonding.  You can hit somebody with a lever but not with magnetic field.  When two magnets interact, the force acts on the base ie., on magnets from which field originates.  On a lever, the force acts on the point of application.  You cannot take distance between magnets as lever length because force acts on the base(magnet).

                I see your point. 

1. Magnetic field is non-physical and is flexible.  true
But any physical lever has also some degree of flexibility.

2. A lever is made of solid material with solid bonding. true
But all physical objects are composed entirely of energy, and
that property which we call solid is energy's tendency to sometimes
persist in stable patterns.  What we perceive as solid and measure as force is
the resistance to change in those patterns of energy.  All physical objects in our world
are composed of vastly more space than substance.

3. You can hit somebody with a lever but not with magnetic field.
You can levitate a frog with a great enough magnetic force.  If you can lift it
you can also smack it.

4. You cannot take distance between magnets as lever length because force acts
on the base(magnet). true
But you can to a degree, take the distance between multiple magnetic poles as
lever length.

In description he has mentioned that,  the rotor slips when excess torque is applied.  A solid lever can take excess torque because of its material strength but a magnetic coupling slips as bondage is not strong.  Hence we may not be able to take any excess torque.
Anyway it is a very interesting experiment.
