A matchbox containing an unknown object is placed on a thin sheet of glass in the experimental set-up shown in the figure.
When the bar magnet moves, it is able to drag the match box along. What is most likely to be found in the matchbox?
A Marble
B Toothpick
C Ten-cent coin
D Steel ball bearing
the match box should certainly contain something magnetic as, when the bar magnet is moved then the match box is also dragged along with it .
