I'm a mechanical engineer enthusiastic about learning electrical engineering and I speak french so I thank you in advance for your comprehension and your help.
I would like to be able to activate an electromagnet to pull a pop-up switch throught a thin stainless steel wall (1 mm or 1/32 inch). I'm using an arduino but I guess an external power source will be necessary.
The magnet need to pull a spring to drain a liquid from a tank.
I know thant it would be easier to use a solenoid valve but I can't change the piping.
I was thinking of a u-shaped metal rod wire copper wiring and a relay but I guess that would need a lot of power. Which way would you recommend to achieve this goal?
Once again thank you for helping a mechanical engineer to convert to the electric engineering!
First of all, wow thank you for all theses excellents answers!
Is there any way for me to give you a positive feedback?
Secondly, the tank is non-magnetic but that is an excellent comment and I will need to be careful.
I think a lot of small magnets would do a pretty good job. This is so simple that I did not think about it.
I will try that and will update my post once I succeed!
