Why does a phonog
When a phonograph record is cleaned, electric charges are produced on the record due to induction. This happens as we rub a cloth on the record, friction causes the induction of charges on the record. This phenomenon is similar to a glass rod being rubbed by a cloth. Now, these deposited charges on the record attract dust particles having neutral charge.
Hence, a phonograph-record attract dust particles just after it is cleaned.
