How could my hard telekinesis work?

So, in my setting, telekinesis is divided into two sub-fields:

• Soft telekinesis allows for precise manipulation of objects but doesn't pack a punch. Newton's third law is negligible for this type.
• Hard telekinesis is a quick burst of force that can accelerate an object in a certain direction, but also creates an "opposing force" of the same magnitude in the opposite direction.
  • Because of this, hard telekinesis "force bursts", usually originate from the side of the wizard, not the wizard directly, save for a few examples.
  • Force bursts dissipate over longer distances, at around 50 meters, the opposing force dissipates much faster.
  • The burst itself is invisible and can only be detected through the air turbulence, it generates and its mechanical interaction with other objects.
  • The burst has a "recharge time", but doesn't seem to consume material components, and can be cast as long as sufficient energy is available.
  • Though somewhat scalable, the only time Anon (the strongest wizard in the setting) used hard telekinesis at its full potential, it sent an adult human male, weighing 89 kg, flying for 4 meters before crashing into a rock at 3.5 m/s (I guess. It may have been faster). The guy survived, but his spine was done for, and now he has to spend the rest of his life in a wheelchair.
  • Note: Hosch250 did the math, and it came out to be at around 610 newtons.

Notes:

• Magic: Magic is a mysterious art, that involves robots, chemistry, physics, and is nearly synonymous with science.
• Telekinesis is the basis of so-called spells. Despite the word's origins, it doesn't involve woo, nor is it the sole doing of the mind. The mind commands an unspecified type of robot, or groups of robots, to execute its will. It's that you can't really see them, that's why it appears to be classical telekinesis.

You're free to use nanomachines, superconductors, and even James, as long as the laws of physics aren't violated.

How could my hard telekinesis work? The rules have been established, but I don't know what mechanism should I use.

How can I generate that much force?
How can I keep it concentrated?-In the next question
