Bi-Metal Mechanism
-
The magnetic thermometer measures with the bi-metal spring mechanism that is in the center of the thermometer. The base of the thermometer is held against a still surface that stays intact because of small internal magnets. The movement of the bi-metal strip will transmit to the pointer that can be easily read.
Magnets
-
Magnets are used throughout the magnetic thermometer. The base of the thermometer case is held by internal magnets. On the back side of the thermometer, the case has magnets on the backside of the case that hold the case magnetically secure against metal surfaces. Magnetic thermometers can be a handy instrument for this reason. The magnet is glued to the back surface of the thermometer and is quiet and sturdy.

Batteries
-
Magnetic thermometers do not require batteries. The batteries are located on the back of the thermometer.
Temperatures
-
The thermometer calculates the rise and fall of temperatures by the small sample of paramagnetic salt. The salt's magnetic susceptibility will be measured. The temperatures will then be calculated, which happens because of the inverse relationship between the two small quantities.
