The launcher can launch the model spacecraft by exerting a magnetic force.
Magnetic force is a force just like gravity that can act across a distance without touching the object that is attracted by it. It should be noted that magnetic attraction is a pulling force.
Therefore, since the launcher wants to make the model spacecraft move without touching it, a magnetic force should be exerted on it. The magnetic force can act as the distance that's required for the objects to move.
