What materials can increase magnetic strength in an electromagnetic coil?

Click For Summary
SUMMARY

The discussion centers on enhancing the magnetic strength of electromagnetic coils, specifically those using soft iron cores measuring 3/8" or 5/16" x 1 1/4". The user seeks materials that can increase magnetic field strength without raising the voltage beyond 3-9 volts DC at less than 1 amp. Magnetite (Fe3O4) is suggested as a potential material for improving magnetic strength. Additionally, contacting solenoid manufacturers for commercially available options is recommended.

PREREQUISITES
  • Understanding of electromagnetic coil design
  • Knowledge of materials science, specifically ferromagnetic materials
  • Familiarity with electrical circuits and voltage specifications
  • Experience with solenoid applications and their components
NEXT STEPS
  • Research the properties of Magnetite (Fe3O4) for electromagnetic applications
  • Explore advanced materials for electromagnetic coils, such as silicon steel
  • Investigate solenoid manufacturers for custom core solutions
  • Learn about the impact of core geometry on magnetic field strength
USEFUL FOR

Engineers, hobbyists, and manufacturers involved in designing or optimizing electromagnetic devices, particularly those focused on enhancing magnetic strength in applications like tattoo machines.

I realize that soft iron is the most common material for this but I am wondering if there is something that will increase the magnetic strength.
Here is what I have.
Two electromagnetic coils in series connected by a yoke with a capacitor in parallel (for spark reduction). Cores are soft iron 3/8" or 5/16" x 1 1/4". The magnets move an armature bar that switches the circuit on/off 80-160 Hz.

I'm am looking for a material that will create a stronger magnetic field without having to increase voltage (3-9 volts DC < 1amp) .

What would the most efficient materials be that are available in those dimensions if one were willing to spend more $.

Are you asking this to improve the magnetic strength of the electromagnetic cores of a tattoo machine?
 
Have you tried contacting any solenoid manufacturers to see if anything is commercially available?
