and at least one vibration sensor configured to sense vibrations arising from said at least one machine and to output vibration signals corresponding to said vibrations, said sensing of said vibrations being performed synchronously with said sensing of said magnetic fields; a signal analyzer comprising at least one data processing module in communication with said at least one magnetic sensor and said at least one vibration sensor and a cloud processing server in communication with said at least one data processing module, said at least one data processing module being configured to control said at least one sensor module in order for said at least one sensor module to perform synchronous magnetic and vibrational sensing, with said signal analyzer being configured to receive at least a portion of said magnetic field emission signals and said vibration signals and to perform analysis of phases of said magnetic field emission signals with respect to said vibration signals, said signal analyzer being configured to provide an output based on said analysis, said output comprising at least an indication of a condition of said at least one machine, wherein phase and amplitude of synchronous magnetic field emission signals and vibration signals are used to ascertain that said at least one machine is in a properly operating, healthy state, and wherein said analysis of phases comprises generating a phase plot for said machine and comparing said phase plot to a respective phase plot of said machine when in a properly operating state, in order to derive said condition; and a control module configured to receive said indication of said condition and to initiate at least one of a repair event on said at least one machine, an adjustment to a maintenance schedule of said at least one machine and an adjustment to an operating parameter of said at least one machine based on said indication, whereby efficacy of said at least one machine is improved, characterized in that: in said phase plot a relative phase of said magnetic field emission signals and vibration signals is plotted against a sum of said magnetic field emission and vibration signals energies. at least one sensor module comprising: at least one magnetic sensor configured to sense magnetic fields emitted by at least one machine and to output magnetic field emission signals corresponding to said magnetic fields;
