Discussion Overview

The discussion centers around the effect of increasing voltage on the strength of electromagnets, exploring the relationship between voltage, current, and magnetic field strength. Participants consider both theoretical and empirical aspects of electromagnet behavior.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the effect of increasing voltage on electromagnet strength and seeks information on the topic.
  • Another participant clarifies whether the voltage refers to that used to generate the current responsible for the magnetic field.
  • Some participants suggest that there is a limit to the magnetization that can be induced in ferromagnets, noting that maximum magnetization occurs when all spins align.
  • Empirical data, such as hysteresis curves, is proposed as a means to calculate the maximum voltage needed for effective magnetization.
  • It is noted that increasing current is likely to increase the magnetic field strength.
  • Some participants emphasize that electromagnets typically have a ferromagnetic core and are designed to achieve saturation, indicating that increasing voltage toward saturation can enhance strength, but further increases may have minimal effect.

Areas of Agreement / Disagreement

Participants express varying views on the relationship between voltage and electromagnet strength, with some agreeing on the saturation concept while others highlight the complexities of ferromagnetic behavior. The discussion remains unresolved regarding the precise effects of voltage increases beyond saturation.

Contextual Notes

Participants acknowledge the complicated nature of ferromagnetism and the lack of a rigorous physical explanation for some behaviors, indicating potential limitations in understanding the relationship between voltage and magnetization.

Hi If anyone know's something about electromagnets. I was wondering if you could either explane to me, or show me where I could find some information about whether or not icreasing the amount of volt's would have an effect on how strong the electromagnet would be. That would be great!

Do you mean the amount of volt used to generate the current that will be responsible for the polarizing magnetic field?
 
I think there's a limit to the amount of magnetization you can induce in a ferromagnet. If you get all the spins to point in the same direction you get maximum magnetization.
In general, ferromagnets behave in a very complicated way. Moreover, I don't even think there's a rigorous physical explanation for how they work. However, you might try using empiric data (hysteresis curves) to calculate the maximum voltage you need.

He's talking about an electromagnet though.
 
Increasing current would probably increase the magnetic field

Electromagnets usually have a ferromagnetic core.
They are usually designed so that the current in the coils will achieve saturation for the core. Increasing the voltage (and hence the current) toward the saturation value will increase the strength. But any voltage increase beyond that would have little effect.
 
Thanks everyone for your help, and explanation. I will be shure to use the information you have given me.
