Hi everyone, I am new here and I am after some help with setting up a variable strength electromagnet for a project where I will be stretching a material. I am beginner so I don’t have any experience with this and was hoping to keep it relatively simple. I simply need to change the pull strength of an electromagnet and power this via mains power and also via a battery at times.
So far I have come up with things I may need:
- 5V Electromagnet- 10kg holding force
- Adafruit Crickit for circus playground express
- Potentiometer (I am not sure which one to use).
It would be great if this was standalone and did not need to use software. Any help with supplies required and how to set this up would be greatly appreciated. Thank you.
