Discussion Overview

The discussion revolves around the determination of the poles of a solenoid when a permanent magnet is brought near it. Participants explore the application of the right hand thumb rule and the identification of magnetic poles based on current flow direction.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes a scenario where a solenoid with 100 turns attracts the North pole of a permanent magnet, raising confusion about the expected behavior according to the right hand thumb rule.
  • Another participant suggests that the original poster may be applying the right hand thumb rule incorrectly and emphasizes the importance of correctly identifying both the poles of the magnet and the solenoid based on current flow direction.
  • A later reply indicates that the participant has identified the poles based on current flow direction but expresses uncertainty.
  • Another participant questions the conventional definition of current flow, noting the potential confusion between the direction of current and the movement of electrons.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are competing views regarding the application of the right hand thumb rule and the identification of magnetic poles.

Contextual Notes

There is a lack of detailed information, such as diagrams or specific current flow directions, which may affect the clarity of the discussion. Additionally, the definitions of current flow and magnetic pole identification remain unresolved.

Hi Everyone,

I have made a solenoid of 100 turns. When i bring a small permanent magnet near the solenoid, it attracts the North pole of permanent magnet while it should attract the South pole according to right hand thumb rule... now i got confused. Kindly help me.

Regards,
hsn

Not enough information to answer I feel. Maybe a diagram can help. But you are definitely applying the right hand thumb rule wrong. Reason could be you mixed up the poles of the magnet, identify them correctly, AND make sure you identify the poles of the solenoid correctly, based on the current flow direction. If these two things are correct, then you should get proper result.
 
Yeah i have identified the poles on the basis of current flow direction... ! but...
 
Don't they define current flowing from positive to negative even tho the electrons are moving. Sometimes I get the direction of current mixed up.
