In figure, how do we think the displacement of rod AB will be affected if (i) current in the rod AB is increased, (ii) a stronger horse-shoe magnet is used, and (iii) length of the rod AB is increased?

In Activity 13.7. how do we think the displacement of the rod AB will be affected if (i)the current in rod AB is increased : (ii) a stronger horse - shoe magnet is used , and (iii) the length of the rod AB is increased ?

A small aluminium rod AB is suspended horizontally from a stand by the ends of two connecting wires as shown in the Figure given here. A horseshoe magnet is placed in such a way that north pole of the magnet is vertically below and its south pole vertically above the aluminium rod. The aluminium rod is connected in series with a battery, a key and a rheostat. How do you think the displacement of rod AB will be affected if : (i) current in rod AB is increased ? (ii) a stronger horseshoe magnet is used ? (iii) length of the rod AB is increased ?

In activity shown, how do you think the displacement of rod AB will be affected :if the current in rod ab is increased,
