Attraction to a magnet is a physical property of matter, not a chemical property. It is based on the arrangement and movement of the electrons within the material, rather than the chemical bonds between atoms. This magnetic property can be observed without changing the chemical composition of the material.
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
iron oxide, which forms a magnetic field when exposed to a magnetic field. This property allows magnetite to be attracted to a magnet.
Magnetism is a physical property that is mediated by magnetic fields.The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.
Heating a bar magnet is a physical change because the magnet does not undergo a chemical reaction. The heat energy causes the atoms in the magnet to vibrate, which disrupts the alignment of the magnetic domains within the magnet, thereby reducing its magnetic strength.
The property of magnetism made it possible to separate the mixture with a magnet. Some components of the mixture may be attracted to the magnet while others are not, allowing for separation based on magnetic properties.

The special property that magnetite displays is that it is attracted by a magnet. Cleavage is the mineral property that explains why some minerals break along smooth, flat surfaces.

The answer is physical:)
No, copper is not attracted to a magnet.

Anything that is attracted to a permanent magnet will be attracted to (sticks to) a temporary magnet.
Some minerals contain magnetite, which is atracted to magnets.
The way that thoughts are attracted to signals like metal to a magnet.
This is not a change at all. However it is physical when you use a magnet to physically seperate (by manetic force) .
