Answer 2

To test that the ‘tea dust’ is not adulterated with iron powder, one may use a magnetic test.

With the help of this test, one may know the status of the tea dust, as if there contains iron powder; it would be extracted from the tea dust with the help of the magnet.

Hence, the magnetic test would be helpful in knowing if tea dust is adulterated with iron powder or not.
