Many of us have noticed that aluminium foil or any other metal for that matter sparks in a microwave. Can you tell why? (please refrain from using internet to find the answer - use your own ingenuity )

Microwaves produce a flow of current in foil.it sparks due to polarisation of highly charged particles and a conductor between them(alluminium). if particles(atomes,molecules) not polarised then foil simply burns without sparking..
yahi laga mujhe to isa explanation... phuysics padhe hue 1 decade ho gya.. sahi reason kya hai ye aap bta do..

Harender jee - you are quite right. Microwave is elctromagnetic radiation that causes electrons in the metal to move and accumulate at the tip of the crumpled aluminium foil. Due to charge accumulation at the tips/high point of the metal, the surrounding air starts sparking. This is my understanding.
