Faraday's first law of electromagnetic induction
Faraday's second law of electromagnetic induction
Fleming's right hand rule
Each piece will become a separate magnet having north and south pole
Magnetic property will be destroyed in both the pieces completely
Longer piece only will have magnetic property with north and south pole on either end
One piece will have only north pole and the other piece will have only south pole
Alnico is having higher retentivity of magnetism.
