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 .

Ans 1:

Tamrashi Pani from National public school, whitefield, banglore
Class : Class 6
Yes it is... yet a steel ball bearing is the best option

Ans 2:

Ans 3:

MIHIKA RAUT from ST JOSEPHS SCHOOL, RIHAND NAGAR
Class : Class 7
steel ball bearing is a conducter that is why it is able to drag the box with it.
