What materials can increase magnetic strength in an electromagnetic coil?

Click For Summary

Discussion Overview

The discussion revolves around identifying materials that can enhance the magnetic strength of an electromagnetic coil, particularly in the context of a specific application involving coils in series with a capacitor for spark reduction. Participants explore potential alternatives to soft iron for the core material, aiming to achieve a stronger magnetic field without increasing voltage.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant notes that soft iron is commonly used but seeks alternatives that could provide a stronger magnetic field without increasing voltage.
  • Another participant questions whether the inquiry pertains to improving the magnetic strength of coils used in a tattoo machine.
  • A suggestion is made to contact solenoid manufacturers to explore commercially available options for enhancing magnetic strength.
  • Magnetite (Fe3O4) is proposed as a potential material for increasing magnetic strength.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best materials to use, and multiple competing views and suggestions remain in the discussion.

Contextual Notes

The discussion does not clarify the specific properties or performance metrics of the suggested materials, nor does it address the implications of using different materials on the overall design and function of the electromagnetic coils.

Who May Find This Useful

Individuals interested in electromagnetic design, materials science, or specific applications such as tattoo machines may find this discussion relevant.

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?
