SUMMARY

The discussion focuses on enhancing the power of a small homemade electromagnet using a permalloy core machined to 17mm long and 2mm in diameter. The user is utilizing a 0.125mm insulated copper wire and a Manson EP-613 power supply (0-30V, 2.5A DC). Key recommendations include calculating the required voltage and current for achieving a force greater than 0.001N while preventing circuit overheating. Design advice and relevant formulas are sought to optimize the electromagnet's performance.

PREREQUISITES
  • Understanding of electromagnet design principles
  • Familiarity with Ohm's Law and electromagnetic force calculations
  • Knowledge of wire gauge specifications and insulation types
  • Experience with power supply specifications and limitations
NEXT STEPS
  • Research formulas for calculating electromagnetic force based on current and core material
  • Learn about the thermal limits of copper wire in electromagnet applications
  • Explore the effects of different core materials on electromagnet strength
  • Investigate techniques for optimizing wire winding to enhance magnetic field strength
USEFUL FOR

Electronics hobbyists, DIY enthusiasts, and engineers interested in electromagnet design and optimization techniques.

Small Simple Electromagnet...Help Please!

hi
I'm trying to make a simple small electromagnet using a core from electric drill transformer (I think its called permalloy if I'm not mistaken) which i machined into 17mm long and 2mm diameter. How can i make it powerful enough to produce a force of more than 0.001N without overheating the circuit. I'm using a 0.125mm insulated copper wire, powered by a Manson EP-613 power supply (0-30V , 2.5A DC power supply)

Can anybody point me to a right direction? Such as formula needed for the calculation of voltage and current needed and advice on the design itself would be appreciated.
