I am running an experiment for my school which investigates the effect of temperature on the magnetic field of a magnet, and I encountered a little problem. For the measurement of data, I have gotten a thermistor and a linear radiometric hall effect sensor and I will be using an Arduino for the data logger. The problem I am facing is that I don’t know how to measure the magnetic field strength and the temperature efficiently without losing a lot of heat.
So far I thought of two methods, however, I am not sure if they will work. One way that I thought of was placing the magnetic in a test tube with water and then heating the water until its boiling point, then remove the head and connect the thermistor to the water and I measure the magnet through the test tube. The second method that I was thinking of was to simply place the magnet in boiling water and then transfer it with ceramic tip tweezers to a little set up with the thermistor and hall effect sensor already placed.
In the first method I feel that the water would not have exactly the same temperature as the magnet at all times, and the glass/water medium will affect the magnetic field strength that I'll be measuring. In the second method I think a lot of heat will be lost through radiation during the transfer; thus the temperature will drop very quickly and the date wouldn’t be accurate. I’m not exactly sure how to heat it up and measure the temperature & magnetic field strength efficiently. I would really appreciate some suggestions/help.
Thank you very much!
P.S I am a High School student thus I do not have access to advance apparatus
