A procedure to measure the magnetic field inside the CMS yoke elements is considered. Fast discharge of the CMS coil can be used to induce voltages in flux loops installed around selected elements of the CMS yoke. By sampling the voltage induced in any one loop, and integrating the voltage waveform over the time of the discharge, the total initial flux in the loop can be measured. The average value of the magnetic field in the yoke element normal to the plane of the flux loop is obtained by dividing the measured value of the flux by the known area enclosed by the loop and the number of turns in the loop.
