How will you test that ‘tea dust’ is not adulterated with iron powder?

AcademicPhysicsNCERTClass 6

By using a magnet bar, it can be checked whether "tea dust\' is adulterated with iron powder or not. When we move an iron magnet over the tea dust then the iron powder will get attracted to the magnet bar if it is adulterated with iron powder, otherwise, the magnet bar will be clean if there is no adulteration with iron powder.
