Abstract: Methods of cementing, cementing compositions made from the methods, and articles manufacturable by the cementing compositions are disclosed. The method can include mixing a cement composition and water to make a cement slurry and applying to the cement slurry an alternating magnetic field of from 25 mT to 60 mT at a frequency from 50 kHz to 200 kHz in order to set the cement slurry. The cement composition can have a cement and an amount of magnetic nanoparticles from 0.01 wt % to 10 wt % relative to the amount of cement (0.01% to 10% BWOC). The magnetic nanoparticles can have a mean particle size determined by Transmission Electron Microscopy (TEM) from 10 nm to 50 nm and a crystallite size determined by the Scherrer equation which is at least an 80% the mean particle size.
