Magnetic force on a magnetic bead
2012 10th IEEE International Conference on Semiconductor Electronics (ICSE), 2012Micron-size magnetic particles are utilized in different bio-applications. Many in-vivo and in-vitro analysis use these particles because of their interesting abilities to attach to biomolecules. The magnetically actuation of magnetic beads is important to confine the area of the specified cell analysis.

Magnetic Force Calculations Applied to Magnetic Force Microscopy
2010In IC failure analysis the detection of currents is often used to indicate the presence of a defective device. One method used for this analysis is the Magnetic Force Microscopy (MFM). Employing this technique measurement errors often occur as for instance due to heterogeneous magnetic tip coatings, fabrication/abrasion errors of the MFM tips and ...

This article reviews the subject of force-free magnetic fields. It critically analyzes the force-free condition, explaining that it behaves properly under Lorentz, parity, rotational, and time-reversal transformations. It refutes the proof that it is impossible to have completely force-free magnetic fields.

Magnetic Field and Magnetic Force
2009In this chapter you meet another field of force, the magnetic field. It is quite different from the electric field. Electric fields produce forces on electrical charges whether they are moving or sitting still. The magnetic field exerts a force on an electric charge only if the charge is moving.

Magnetic Forces and Magnetic Media
1975The basis of electrical machines is the interaction of the magnetic field and current-carrying conductor in producing mechanical force. In this context magnetic materials and magnetic circuits play an important part. Our previous discussion has been limited to magnetic effects, mainly in free space, which arise from conduction-type currents. Now, after

Magnetic forces for medical applications
IEEE Transactions on Magnetics, 1969The force that a magnetic field gradient can exert on a ferromagnetic material can be utilized in a number of medical applications. This force is proportional to the spatial gradient of the ambient magnetic field times the magnetic moment of the material; the magnetic moment is a function of the magnitude of the ambient field and the geometry and ...

Magnetic force and magnetic induction.
1998Abstract We have already (art. 385) determined the magnetic potential at a given point due to a magnet, the magnetization of which is given at every point of 1ts substance, and we have shewn that the mathematical result may be expressed either in terms of the actual magnetization of every element of the magnet, or in terms of an ...
