SUMMARY

The discussion centers on achieving high speeds using solenoids to propel lightweight objects, specifically targeting speeds of 2 to 3 meters per second. Key considerations include the material of the object, the presence of friction, and the acceleration length. A proposed method involves using a soft iron rod within a solenoid, which, when energized, can propel a non-magnetic rod that strikes the projectile. This setup effectively utilizes electromagnetic principles to achieve the desired propulsion.

PREREQUISITES
  • Understanding of solenoid operation and electromagnetic principles
  • Knowledge of materials science, particularly regarding magnetic and non-magnetic materials
  • Familiarity with basic mechanics, including friction and acceleration concepts
  • Experience with project design and prototyping
NEXT STEPS
  • Research solenoid design specifications for optimal performance
  • Explore materials suitable for lightweight projectiles and their impact on speed
  • Investigate methods to minimize friction in propulsion systems
  • Learn about the application of magnets in accelerating objects, particularly using niobium magnets
USEFUL FOR

Engineers, hobbyists, and researchers interested in electromagnetic propulsion systems, particularly those working on lightweight object acceleration projects.

I am designing a project that requires propelling a very light object (milligram weight) to speeds of 2 or 3 meters per second is this possible? Small size and voltage of solenoid a big plus.

Too little information. Of course it is possible, after all your electric motors run on solenoids. But the real questions are:

What material is the object made of? Why are you thinking about a magnetic system? Can the object be in contact with a lever? Is there friction? Over what length do you accelerate? Are you accelerating against gravity? Will the object carry its own solenoid? Will the object be made of metal? Does the object need to stay at that speed or can it be pulled against a magnet? I imagine with a large niobium magnet iron particles could reach that speed on the last mm. 100 km/h is not that fast.
 
You could try something like this:

A solt iron rod is pulled into a solenoid when power is applied.

A non magnetic or insulating rod, attached to the soft iron, protrudes out of the other end of the solenoid.
This hits the projectile with a lot of force projecting it off to the right in the diagram.
