Editing Magnetohydrodynamics (section)

===Magnetic drug targeting===
An important task in cancer research is developing more precise methods for delivery of medicine to affected areas. One method involves the binding of medicine to biologically compatible magnetic particles (such as ferrofluids), which are guided to the target via careful placement of permanent magnets on the external body. Magnetohydrodynamic equations and finite element analysis are used to study the interaction between the magnetic fluid particles in the bloodstream and the external magnetic field.<ref>{{Cite journal|last1=Nacev|first1=A.|last2=Beni|first2=C.|last3=Bruno|first3=O.|last4=Shapiro|first4=B.|date=2011-03-01|title=The Behaviors of Ferro-Magnetic Nano-Particles In and Around Blood Vessels under Applied Magnetic Fields|journal=Journal of Magnetism and Magnetic Materials|volume=323|issue=6|pages=651–668|doi=10.1016/j.jmmm.2010.09.008|issn=0304-8853|pmc=3029028|pmid=21278859|bibcode=2011JMMM..323..651N}}</ref>
