I was wondering what exactly a solenoid is and what it can do or does do. Also how it works, as in if you supply a specific current/voltage or whatever will it pull/push ( or whatever it does).

any help appreciated.

A solonoid is a coil of wire that acts as an electromagnet. When voltage is applied, a metal shaft moves through the coil. Here are some pictures.

If i supply the appropriate voltage/current, will this activate the solenoid or does it need extra components?? solenoid do push or pull right?

thx

 

No, you don't normally need extra components - you would normally apply a DC voltage to it, as AC would cause it to be constantly reversing it's poles. Some solenoids, however, are designed for AC use.

 

oh I see, thx alot for your help guys. Very useful site as well Gene!!!

Here is an interesting project I just found that uses a solenoid: The Vortex Cannon.

 

seems like a NICE project. ty all
