Motion of a charged particle in a magnetic field
Hitherto, we have focussed on applications of quantum mechanics to free particles or particles confined by scalar potentials. In the following, we will address the influence of a magnetic field on a charged particle. Classically, the force on a charged particle in an electric and magnetic field is specified by the Lorentz force law: Hendrik Antoon Lorentz 18531928 A Dutch physicist who shared t...
متن کاملMAGNETIC RESONANCE Complement FIv SPIN 1/2 PARTICLE IN A STATIC MAGNETIC FIELD AND A ROTATING FIELD: MAGNETIC RESONANCE
In chapter IV, we used quantum mechanics to study the evolution of a spin 1/2 in a static magnetic field. In this complement, we shall consider the case of a spin 1/2 simultaneously subjected to several magnetic fields, some of which can be time dependent, as is the case in magnetic resonance experiments. Before attacking this problem quantum mechanically, we shall briefly review several result...
متن کاملParticle size, magnetic field, and blood velocity effects on particle retention in magnetic drug targeting.
PURPOSE A physics-based model of a general magnetic drug targeting (MDT) system was developed with the goal of realizing the practical limitations of MDT when electromagnets are the source of the magnetic field. METHODS The simulation tracks magnetic particles subject to gravity, drag force, magnetic force, and hydrodynamic lift in specified flow fields and external magnetic field distributio...
متن کاملStraight and Circular Motions of a Particle in the Field of Two Fixed Attractors
Abstract. The two centre problem is studied both in the phase plane and in spacetime, assuming first a trajectory collinear, and, as a second case, a circular one through the newtonian attractors, finding a saddle equilibrium. For the latter problem a probably new differential equation is met and solved. Time is then obtained in both cases through elliptic integrals of all kinds and Jacobian fu...
متن کاملIllustrating Magnetic Field Lines using a Discrete Particle Model
In this paper we demonstrate how a computational physics approach based on a discrete particle model can be employed for the visualization of magnetic field lines. This can be regarded as an illustration technique for the underlying vector field. To accomplish this, a model for ellipsoidal shaped particles consisting of ferromagnetic materials is described in combination with a parallel simulat...
