Electromagnetic Flight ?

'Basics of Electronics'

by Elmar Dehler & others.
REA 2012. EUROPA LEHRMITTEL.

(this book has a chapter about electricity, magnetism & Lorentz force).


'Waves & Antennas'

by Jarosław Szóstka.

(this book has chapters about electromagnetism,
also about waves & about energy in electromagnetic fields).

'Electromagnetic propulsion (EMP), is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields.

The electrical current is used to either create an opposing magnetic field, or to charge a fluid, which can then be repelled.

When a current flows through a conductor in a magnetic field, an electromagnetic force known as a Lorentz force, pushes the conductor in a direction perpendicular to the conductor and the magnetic field.

This repulsing force is what causes propulsion in a system designed to take advantage of the phenomenon.

The term electromagnetic propulsion (EMP) can be described by its individual components: electromagnetic- using electricity to create a magnetic field (electromagnetism), and propulsion- the process of propelling something.

One key difference between EMP and propulsion achieved by electric motors is that the electrical energy used for EMP is not used to produce rotational energy for motion; though both use magnetic fields and a flowing electrical current.'

Questions:

1. can this be used to propel small flying objects such as Milimetrites (Mili Electro Mechanical Systems; a milimeter is 10-3 of meter), MEMS (Micro Electro Mechanical Systems; a micrometer is 10-6 of meter) devices or perhaps even NEMS (Nano Electro Mechanical Systems; a nanometer is 10-9 of meter) devices ?
2. can the flight vector be chosen that way ?

i am not an expert yet, but i think i should answer these questions a certain day in a future.

imagining however:
- perhaps ionizing air, creating plasma, makes coordination of NEMS nanites quite a daunting task, aside from software's inherent complexity,
- because of charged air or other medium, as well as plasma, pressure on objects can be of kinetic nature (particle collisions) or of electromagnetic nature, perhaps of yet another type(s) as well,
- how to handle wireless communication between devices as well ? this also leaves space charged as the wireless signal is also an electromagnetic wave,
- perhaps precalculating 'cases' for different energy fields will be neccessary.
