Explain that magnetization of an iron nail is a physical change?

Answer 1

It is a rearrangement of the atoms already present, without changing their form chemically.

An atom's atomic structure can change due to an electron's gain or loss, which causes a chemical change.

Magnetization does not alter the chemical composition or structure of the iron atoms; rather, it merely aligns the existing iron atoms in a particular way owing to the effect of a magnetic field on their dipole characteristics.

Since atoms are rearranged without their chemical makeup changing, magnetization of an iron nail is a physical change.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
