Classical Interaction of a Magnet and a Point Charge: The Classical Electromagnetic Forces Responsible for the Aharonov-Bohm Phase Shift
A new classical electromagnetic analysis is presented suggesting that the Aharonov-Bohm phase shift is overwhelmingly likely to arise from a classical lag effect based upon classical electromagnetic…

A new cantilever beam-rigid-body MEMS gyroscope: mathematical model and linear dynamics
A new microbeam-rigid-body gyroscope is introduced and its static and dynamic behaviours are studied. The main structure includes a microbeam and an eccentric end-rigid-body influencing the dynamic…

Classical Interaction of a Magnet and a Point Charge: The Shockley-James Paradox
It is pointed out that Coleman and Van Vleck make a major blunder in their discussion of the Shockly-James paradox by designating relativistic hidden mechanical momentum as the basis for resolution…

Interaction of a Magnet and a Point Charge: Unrecognized Internal Electromagnetic Momentum Eliminates the Myth of Hidden Mechanical Momentum
A model calculation using the Darwin Lagrangian is carried out for a magnet consisting of two current-carrying charges constrained by centripetal forces to move in a circular path in the presence of…

Self-Inductance and the Mass of Current Carriers in a Circuit
In this article, the self-inductance of a circular circuit is treated from an untraditional, particle-based point of view. The electromagnetic fields of Faraday induction are calculated explicitly…

Nano and viscoelastic Beck's column on elastic foundation
Beck's type column on Winkler type foundation is the subject of the present analysis. Instead of the Bernoulli-Euler model describing the rod, two generalized models will be adopted: Eringen…

Analysis of nonlinear dynamics of a cantilever beam-rigid-body MEMS gyroscope using a continuation method
The nonlinear dynamics of a microbeam-rigid body gyroscope are investigated by using a continuation method. To study the nonlinear dynamics of the system, the Lagrangian of the system is discretized…

Eigenvalue analysis of a cantilever beam-rigid-body MEMS gyroscope
The eigenvalues of a new microbeam-rigid-body gyroscope are computed and studied to show the variation of frequencies versus the input spin rate. To this end, assuming the harmonic solution of the…

Magnetic Torque of Microfabricated Elements and Magnetotactic Bacteria
We present a thorough theoretical analysis of the magnetic torque on microfabricated elements with dimensions in the range of 100 to 500 μm and magneto-somes of magnetotactic bacteria of a few μm…

Tracking the radiation reaction energy when charged bodies accelerate
We address some questions related to radiation and energy conservation in classical electromagnetism. We first treat the well-known problem of energy accounting during radiation from a uniformly…

A Novel Variational Principle in Electrostatics and its Consequences
We propose a novel variational principle in electrostatics and show that one can derive mirror equation in the context of image problem starting from this principle. The corresponding Euler-Lagrange…

Understanding rigid body motion in arbitrary dimensions
Why would anyone wish to generalize the already unappetizing subject of rigid body motion to an arbitrary number of dimensions? At first sight, the subject seems to be both repellent and superfluous.…

A Topological Structure in the Set of Classical Free Radiation Electromagnetic Fields
The aim of this work is to proceed with the development of a model of topological electromagnetism in empty space, proposed by one of us some time ago and based on the existence of a topological…

Ambiguities in order-theoretic formulations of thermodynamics
Since the 1909 work of Carathéodory, formulations of thermodynamics have gained ground which highlight the role of the the binary relation of adiabatic accessibility between equilibrium states. A…

Predicting Non-Square 2D Dice Probabilities
The prediction of the final state probabilities of a general cuboid randomly thrown onto a surface is a problem that naturally arises in the minds of men and women familiar with regular cubic dice…

Self-force of a rigid ideal fluid, and a charged sphere in hyperbolic motion
