Help me make a Solenoid Magnet

a solenoid like you linked to; https://music.columbia.edu/~douglas/c...mania/sol4.jpg
is used in a lot of automatic washing machines. To shift the mechanism from agitate to spin.

Not knowing to much about the Philippines, are there any scrap yards or junk yards in your area? Or even appliance repair shops? You could have a look and see what you can find there. Being from the area it would be the correct voltage too.

are you refering this kind of solenoid? which runs on AC?

its a revolving motor not the PUSH and PULL type, i open up our washing machine which broken for quite sometime now.

sound you are not trying any sugestions by others, provide the follwing details 1st
1) how much is the resistance you measure between terminals?
2) what is the dificulty for you to change the size of the wire?
3) have you understood the idea how the calculations must be?

i know your problem is very simple but you are still strugling, say a nominal size of solenoid can stand a loss of 5W that can be discipated to atmosphear keeping a small temperature raise.

just checked you pictures, the idea of your plunger is wrong, you have kept the same airgap through out, so you cannot expect any usefull force from it, it will just adjust to keep its position on its centre. that may be the dificulty you faced when used low voltages.just look some standard solenoids how they are made, normally plunger will be the same length of the solenoid, but some portion is brought out with spring load so when energized it will completely go inside and it decides its stroke.

if you need a push one you have to have a extended small rod like a needle of (2mm dia) comming from teh same size of plunger as discribed above. see the picture attched

There should be several solenoids in your washing machine. Here are some generic parts; Washing Machine Solenoid Parts from RepairClinic.com

You are going to have to do the searching inside your machine, I'm not there to do it for you!

You seem to have Internet so do a Google search for a parts schematic on the washer you have and see where the solenoids are in it.

Even the hot and cold water inlet valves are solenoids. You would just need to remove the valve parts and use the solenoids to do what you want.
