Yes they are made of the same elements, but in different proportions and they are both known as iron oxides being mixtures of iron and oxygen.
Magnetite is FE304, whereas hematite is FE203.
It is easy to give an example of how different amounts of elements can radically change compounds by thinking about water - H20. Water is non-flammable, but two-thirds of its constituent elements is the highly flammable hydrogen.
The same principle applies to magnetite and hematite.
