In the study of ways to determine the position of and manipulate magnetic nanoparticles – a capability that would benefit a wide range of applications – theres good news and bad: While a magnetic gradient force field (a magnetic field that varies with respect to position) can accomplish this, it is limited in its ability to affect most paramagnetic materials – that is, materials that respond to magnetic fields, but do not retain magnetic properties when those fields are removed – the exception being sufficiently small magnetic nanoparticles, which can behave like paramagnets at room temperature due to thermal agitation (an effect known as superparamagnetism).
