Problem in determinig Poles of a Solenoid

[hsn1]

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.
