We now extend our calculations for MNPs from exact magnetic substance but diverse diameters on the magnetic core. The Power Em of nanoparticle is straight proportional to its magnetic instant mp plus the applied area H, where by mp is proportional on the particle magnetization, its density and its volume https://lingjunbio.quora.com/Lnjnbio-Magnetic-Beads-for-Plasmid-DNA-Extraction-and-Purification-160024-Home-https-www-lingjunbio-com-Products
