1.	In Activity 13.7 (NCERT Textbook), how do we think the displacement of rod AB will be affected if (i) current in rod AB is increased, (ii) a stronger horse-shoe magnet is used, and (iii) length of the rod AB is increased ?
Answer» Solution :(i) On INCREASING the current in rod AB its displacement will increase. (ii) If we use a STRONGER horse-shoe MAGNET then the displacement of rod AB will increase. (iii) If length of the rod is increased, force ACTING on it will increase and, hence, displacement of the rod increases.
