Hi im new in this forum and im about to design an electromagnet to pick up coins. As i know the coil will gets hot when current flows.
The battery that will be use is 4x1.5V size AA.
My question is,
- Do i need a current limiting circuit to avoid the coil from getting hot ?
- What other ways can i do to overcome the coil from getting hot as long it can produce good magnetic strength ?
Thanks...
