Answer 1

Heya !!

Here is your answer
=========================================

When we mix some iron pellets in a mixture of sand and gravel, it is a type of physical change. We can get back iron pallets by bringing a magnet near to the mixture. All the iron pellets will be sticked to the magnet. Thus it is a type of physical change.

Answer 2

Yes it is physical as no new substance is formed and we can use physical methods to separate the mixture
Iron can be separated using magnets and gravel by hand picking
