I have found different equipments in literature to measure the magnetization of solid samples. But, most of them seem to require big set-up or expensive. Can anyone suggest me some simple way/equipment to measure magnetization of samples?
I suggest using Gouy balance. All what you need is balance, magnet with flat and parallel surface and a glass tube.

My suggestion is a vibrating sample magnetometer. With this tool, you can learn a lot about the magnetic properties of your material ( hystersis loops, coersive field, remanence, saturation field etc.) If you have an oven/ cooler attached, you can even find out about the temperature dependence of your magnetic material.

Dear Musfique Ahmed
In the laboratory we used three magnetometers:
VSM - Vibrating Sample Magnetometer;
AGFM - Alternative Gradient Field Magnetometer;
MOKE - Magneto-Optical Kerr Effect;
With any of them you can perform magnetization measurements.
Oreci Escobar Da Silva Thank you. Which of this instrument has the option to measure magnetization with high temperature? I mean if I want to see the changes of magnetization of my sample with temperature, then which magnetometer I should use?
Musfique Ahmed In the three magnetometers I mentioned, to make measurements using temperature variation, I know only in adapted magnetometers, I recommend you use a magnetometer that is usually specific to working with temperature variations under the sample "SQUID". SQUIDs are a type of magnetometer used both as survey and as laboratory magnetometers. SQUID magnetometry is an extremely sensitive absolute magnetometry technique. However SQUIDs are noise sensitive, making them impractical as laboratory magnetometers in high DC magnetic fields, and in pulsed magnets. Commercial SQUID magnetometers are available for temperatures between 300 mK and 400 kelvins, and magnetic fields up to 7 tesla.
