VAILLANT LOPEZ, Nuria de los Ángeles; CARRERAS FERNANDEZ, Gabriela  e  RIBEAUX KINDELAN, Guillermo. Effects of the magnetic field on the total hardness, specific heat and boiling point of water. Ing. hidrául. ambient. [online]. 2022, vol.43, n.4, pp. 76-87.  Epub 23-Mar-2023. ISSN 2788-6050.

To examine the effect of the magnetic treatment (MT), in the total hardness (TH), point of boil (PB) and capacity of conservation of heat (CC) of the water of the source ¨Cosculluela¨, of Havana, the samples were subjected to a magnetic field (MC) generated by permanent imams, NOVAMAG marks, for three values of intensity of MC (325 mT, 268 mT y 2 17 mT), speed of circulation of 0,073 m/s, three times of exhibition (1,09s, 2.18s, 3.27s) and ambient temperature (22 ±1°C). Variations were obtained in the TH, the PB and the CC of the samples with MT. As for the magnetic memory, in the periods of 48h and 72h they stayed the effects caused by the MC for the Pb and the CC but didn't for the TH.
