I recently purchased some inexpensive 110Volts AC solenoid coils from China through eBay (of course.)
As I understand solenoids will convert electricity into linear motion. I have been unable to do that. I tried ferrous rods as plungers, they get stuck inside the walls of the coil's cylinder. No ferrous material like aluminum rod did not work at all. Can someone please guide me to make it work. I purchased 110 Volt coil thinking that it will create a stronger field, I don't feel the strengths of magnets to be rather weak.
1. The coil gets hot when energized. Will it burn out if I keep the solenoid energized for 4-5 minutes?
2. Should I go for a lower voltage DC coil?
3. What happens to the dc coil if energized for long time?
I would greatly appreciate your comments.
