I want to remove the core from a flyback transformer?
For experimental purposes i want to remove the ferrite core from a flyback transformer. I want to be able to remove it without damaging the primary or secondary windings. I don't care if the core is ruined. Someone suggested boiling the transformer in water. Has this been successfully done or is this an untried suggestion?

Keep the cores, because you can actually use them to make any large ferrite transformer or choke.

I have done this a few times by first prying off the metal clip, and using alcohol to break up the glue, and wiggling and pulling on the core to get it to come off. Generally the top half will come off first and easy. Then with the flyback sitting on a surface, I gently but firmly apply a lot of pressure to the core from the inside of the coil with a rod. Heating up the core will help.

In most cases it won't work as expected with water.
I put mine in the oven at 200°C for about 30-40min - this will soften the glue enough so the two halfs can be seperated but you still need to remove the metal clip first.
