Hello
I need help for building magnet with winding that can stick on Iron
and this circuit must be controlled by Microcontrollers:razz:

break a relay and take out the electromagnet from there.
I Test it ,but it's very weak
You cant use relay coil for that. Relays dont have that power magnetic field, its designed just to move small iron with platine contacts. Relay have thin wires on coils, you need higher current and higher magnetic fields.
thanksYes, but that current you can put into relay coil.
Make strong and light coils. Consider permanent magnet rolling tecnique.

Save power in batteries. If you add more weight on robot with more iron and more batteries to get more and stronger magnetic field, it will be very heavy. Think in other direction....
