CLASS 7 ACTIVITY, OBSERVING MAGNETIC FIELD LINES AROUND A BAR MAGNET USING IRON FILINGS

                                               Magnetic field lines around a bar magnet














                                           Same poles of magnets facing each other

Opposite poles of magnet facing each other

Students of class 7 observed the magnetic field lines using iron fillings and bar magnet.
They placed a bar magnet and covered it with a white paper , then sprinkled it with iron fillings.
iron fillings align themselves according to the magnetic field.
Also, Students place two bar magnets with same poles facing each other and with opposite poles facing each other and observed the magnetic field lines
