if the area increases woth time then the magnetic force increases and when does it stop?

dude it will stop due to the frictionsl force between the wire and the metallic strios

i know it may stop due to friction but what i ask is force is to the rifgt side! yes,friction is to the left magnetic force is given by iAB here if the rod moves then area will increase and hence force! then how does friction stop the rod

by right hand palm rule no 2 the magnetic force is towards right so slight increase in area(dx) force is increased ny i(dx)Bb and here dx is increasing and hence force will be increasing

you keep forgetting the back emf which will be induced in the wire
