Whether it exerts a force on ferromagnetic objects.
The density of the substance.
a magnet Actually named magnetite, but it is a natural magnet.
the thing that determines it is the type of molecules that are in the substance
No because it is an inert substance.
It determines the mass of the substance per unit volume.
It determines the mass of the substance per unit volume.
A magnetic substance can also be made into a magnet by aligning its magnetic domains in the same direction. This alignment creates a magnetic field around the substance, allowing it to attract or repel other magnetic materials. The strength of the magnet depends on the material and the alignment of its domains.
The magnet by itself would not kill you. However... If the magnet was sharp or pointy it could cut or perforate your digestive tract, which could kill you. If the magnet was too large to pass through your digestive tract it could cause a fatal obsruction. If the magnet was coated with a toxic substance, that substance could kill you.
This property is called chemical reactivity.
Solubility
Magnets are made by lodestone. If the magnetic qualities of lodestone are passed in a magnetic substance, then it will be a permanent magnet.
