Sorry for the delay. (Likely Spam problem)
Electromagnetism is a large field of physics.
So, I guess these are some common mistakes of students:


  • Which is left hand, right hand.
  • Right-hand rule, Fleming's left-hand rule. (Which is direction of electric current, magnetic, force)
  • Field line (the direction from north pole to south pole for outside field and south pole to north pole for inside field)
  • Electromagnetic induction in a coil (the pole and moving direction of a magnet affect to the direction of electric current inside the coil).
  • Electromagnetic induction in a fluid flowing coil.
