Magnetic materials undergo phase transition which from non-magnetic to magnetic as the temperature is decreased. Phase transition temperature is one of the characteristics and can be determined from specific-heat measurement. The other is, type of the magnetic state or the magnetic susceptibility. Magnetic susceptibility can be measured in magnetometers such as VSM, SQUID etc.

The magnetic structure can also be determined from neutron diffraction.

Magnetic properties is a general statement. Have you an idea of what you are interested to? However, the most diffused way is to use magnetometers as SQUID or VSM

Dear Mr. Riyadh Saeed Agid,

It depends on the composition of the material. Magnetic materials are classified based on the materials having a permanent magnetic moment or not. Therefore, my suggestion is to undergo a literature survey based on your composition of the material and then you may know more information related to the magnetic behaviours. Based on the survey, we may check the magnetic properties with the available techniques/instruments

With regards,

OK - interesting - several ways to look at this. #1 - are these samples actual magnets or parts of a broken magnet? Can you tell where the magnet poles are?

One of the most common situations where this question occurs is a motor has a magnet that comes apart or breaks and someone needs to replace it but, since it is broken they are not sure what it is.

A less common would be if you actually ordered magnets but are not sure what it is and you want to make sure is - like you may think it is N50but someone tells you they think it is a lot weaker. That type of question requires more extensive test equipment .

Dear Snehadri Bihari Ota

thank you for your answer.

Thanks

Hi Dear

If your samples belonging to the family of magnetic materials then my suggestion is to do VSM or SQUID at different temperature. After that you calculate remanant magnetization, saturation magnetization and many more.
