Higest speeds possible from solenoids

• Grego Howard
In summary, the conversation discusses the possibility of propelling a very light object at speeds of 2 or 3 meters per second using a solenoid. The use of a small size and voltage of the solenoid is seen as a positive factor. However, there are questions about the object's material, the necessity of a magnetic system, the presence of friction, the length of acceleration, and the effects of gravity. The idea of using a large niobium magnet to reach the desired speed is also mentioned. The conversation concludes with a suggested design involving a solenoid and a non-magnetic or insulating rod to propel the object with force.

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.

1. What is the maximum speed that can be achieved with solenoids?

The maximum speed that can be achieved with solenoids depends on various factors such as the size and design of the solenoid, the type and strength of the magnet used, and the power supply. Generally, solenoids can reach speeds of up to 10 meters per second.

2. How does the size of a solenoid affect its speed?

The size of a solenoid can affect its speed in several ways. A larger solenoid will typically have a longer stroke length, allowing for a longer travel distance and potentially higher speeds. However, a larger solenoid may also require more power to operate, which can affect its speed. Additionally, the design of the solenoid, such as the number of turns in the coil, can also impact its speed.

3. Can the speed of a solenoid be increased?

Yes, the speed of a solenoid can be increased by using a stronger magnet, increasing the power supply, or optimizing the design of the solenoid. However, there are limitations to how much the speed can be increased without compromising the functionality and efficiency of the solenoid.

4. Are there any limitations to the speed of solenoids?

While solenoids can achieve high speeds, there are some limitations to consider. The speed of a solenoid may be limited by the strength of the materials used, the maximum voltage of the power supply, and the physical constraints of the surrounding environment. Additionally, the speed of a solenoid can also be affected by factors such as friction and inertia.

5. Are there any safety concerns when operating solenoids at high speeds?

Yes, there are some safety concerns to consider when operating solenoids at high speeds. The high velocity and force of the moving components can pose a risk of injury if proper precautions are not taken. It is important to follow safety guidelines and use appropriate protective equipment when working with high-speed solenoids.
