You and Mahesh sir are teaching very nicely (keep it coming!!) :D

Then why the screen does not work when some other conducting material like a needle is used!?

[@8BitGamerYT1]

Oh...never imagined it would be like that

[@stevegaming112]

Where is Mahesh sir??

[@ChillPard]

I have the same q, Why did they change teachers in middle of a lesson tho?

[@rihamission487]

Does this suggest that my touch screen will stop working if the phone is near a strong magnetic field? And How come when I touch my screen with a random metal conductor (say a metal rod), it doesn't detect a touch?
