Magnetic field of an inside out electromagnet?

Click For Summary

Discussion Overview

The discussion explores the concept of an electromagnet with its core positioned externally, specifically examining how the magnetic field would be structured in this configuration. The focus includes theoretical implications and the nature of magnetic field generation.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant questions the appearance of the magnetic field when an electromagnet's core is on the outside, suggesting a unique configuration.
  • Another participant inquires about the source of the magnetic field, asking whether it is generated by the coils or the material around which the coils are wrapped.
  • A subsequent response asserts that in this scenario, the coils are responsible for generating the magnetic field.
  • A later reply prompts further consideration about the implications of the previous statements regarding the magnetic field's characteristics.

Areas of Agreement / Disagreement

Participants express differing views on the source of the magnetic field, with some asserting it is the coils while others raise questions about the role of the surrounding material. The discussion remains unresolved regarding the implications of the external core configuration.

Contextual Notes

There are unresolved assumptions about the specific configuration of the electromagnet and how it influences the magnetic field, as well as the definitions of terms used in the discussion.

What if an electromagnet's core is on the outside? How would it's magnetic field look? (The wire being wrapped in coils on the inside of a tube or pipe looking metal)

What generates the magnetic field? The coils or what the coils are wrapped around?

It would be the coils in this case
 
OK, so what does that suggest about the answer to your question?
