PROBLEM TO BE SOLVED: To reduce the total quantity of heat intruding into a container by reducing the opening of the container. SOLUTION: The magnetic measuring apparatus comprises a plurality of magnetic field sensors 40 housed in a cooling container 12 along with a coolant, a support 26 for mounting the plurality of magnetic field sensors 40 removably, and means 30, 34 for mounting the support 26 carrying a plurality of the magnetic field sensors 40 removably on the measuring surface of cooling container 12. Opening of the cooling container 12 is set smaller than the measuring surface for mounting the sensor support 26. |
