Electromagnet, current vs voltage, same?

Click For Summary

Discussion Overview

The discussion revolves around the comparison of two electromagnets operating at different voltage and current levels, specifically examining whether they would produce the same strength. The focus is on the implications of wire gauge and voltage on electromagnet strength, without the ability to change the number of turns in the coil.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether an electromagnet powered by 10vDC at 10amp would be stronger than one powered by 100vDC at 1amp, given the constraint of not changing the number of turns.
  • Another participant states that the strength of the magnet is proportional to the product of amps and turns, implying that the current plays a significant role in determining strength.
  • A later reply suggests that the 10v at 10amp configuration would yield a stronger electromagnet, estimating it to be ten times stronger based on the earlier claim about proportionality.
  • One post was deleted, indicating a change in understanding regarding the ability to alter wire gauge.

Areas of Agreement / Disagreement

Participants express differing views on the strength of the electromagnets based on the provided voltage and current, with some suggesting a clear advantage for one configuration over the other. The discussion remains unresolved regarding the definitive strength comparison.

Contextual Notes

Participants have not reached a consensus on the impact of wire gauge changes on electromagnet strength, and assumptions regarding the relationship between voltage, current, and strength are not fully explored.

Would these two electromagnets be the same strength? I can NOT change turns, I can only change wire gauge and voltage.
What are the advantages if any of either one?

Electromagnet with at: 10vDC at 10amp - VS - 100vDC at 1amp

The strength of the magnet is proportional to (amps * turns).
 
Oh ok that answers my question then. 10v at 10amp would be 10x times stronger then. Thanks
