Entropy and the Stirling engine

Romanelli, Alejandro

2024 European Journal of Physics

doi:10.1088/1361-6404/ad312d

The thermodynamic approach developed in the Romanelli (2017 Am. J. Phys.85 926–31). achieves, among other things, an adequate description of the experimental pressure-volumes diagrams of Stirling engines. However, an unusual and relevant result of such an approach is that, during part of its...

The magnetic field does not perform work—or does it?

Schmidt, Heinz-Jürgen; Bröcker, Thomas

2024 European Journal of Physics

doi:10.1088/1361-6404/ad37e4

We investigate the question discussed in the literature as to whether the magnetic field can perform work using two models that describe interacting magnetic dipoles. In the first model, the dipoles are realized by rigidly rotating charge clouds, whereas in the second model, one of the two...

Factoring 15 with a remote quantum computer: a complete guide for beginners

Brody, Jed; Gram, Kristen

2024 European Journal of Physics

doi:10.1088/1361-6404/ad32dc

We present, for the non-specialist, an experimental implementation of Shor’s factoring algorithm. We are unaware of any other single reference that explains, in a beginner-friendly way, complete circuits that implement Shor’s algorithm. We perform the experiment with IBM quantum processors, which...

Eponyms in physics: useful tools and cultural heritage

Gabovich, Alexander M; Kuznetsov, Volodymyr I

2024 European Journal of Physics

doi:10.1088/1361-6404/ad2fd7

The recent proposition to eliminate eponyms from physical publications is discussed. The role of eponyms in research and education is analyzed. We show that eponyms constitute an integral part of physical texts and ensure the continuity of scientific research. Their proposed elimination is...

Fresnel–Arago laws: an easily feasible demonstration and laboratory exercise for students

Ivković, Saša S; Jovanović, Jelena S; Obradović, Bratislav M

2024 European Journal of Physics

doi:10.1088/1361-6404/ad312f

The basic premise of this work was to create a simple experimental setup for the demonstration of Fresnel–Arago laws and the realization of an experimental exercise. An Iceland calcite is used as a beam splitter, and by adding a diverging lens (commonly used to magnify the image), a large image...

How often does unguided peer interaction lead to correct response consensus? An example from conceptual survey of electricity and magnetism

Ghimire, Apekshya; Singh, Chandralekha

2024 European Journal of Physics

doi:10.1088/1361-6404/ad336c

In this research, we investigated the impact of peer collaboration and changes from individual to group performance of graduate students on the conceptual survey of electricity and magnetism (CSEM) without any guidance from the instructor. We define construction of knowledge as a case in which...

Maximal submergence in dense granular suspensions

Williams, Hollis

2024 European Journal of Physics

doi:10.1088/1361-6404/ad2aa2

How far can a person sink downwards in quicksand? Experience would seem to suggest that there is low risk of submerging completely, but it is not easy to demonstrate this because of the complex rheology of granular suspensions. We study several mathematical models for the sinking of a vertical...

Teaching about non-deterministic physics: an almost forgotten fundamental contribution of Marie Curie

Margaritondo, G

2024 European Journal of Physics

doi:10.1088/1361-6404/ad312e

The first historical steps of radioactivity research offer an excellent opportunity to teach a key concept of modern physics: non-deterministic phenomena. However, this opportunity is often wasted because of historical misconceptions and of the irrational fear of radioactive effects. We propose...

Exploring magnetic interactions between magnets and a magnetizable alloy

Machado, Natália Alves; Cruz, Frederico A O; Hahn, Marcelo; Carvalho, Paulo Simeão

2024 European Journal of Physics

doi:10.1088/1361-6404/ad312c

Traditional problems in mechanics usually involve forces that generate motions described by analytical solutions, easily obtained from differential equations. However, when magnetic forces are involved, problems can be very complex to describe analytically. In this paper, we describe the...

Configurations of dipoles, moving charges and currents for dynamic spherical multipoles

Majic, Matt; Geris, Sophia

2024 European Journal of Physics

doi:10.1088/1361-6404/ad336a

Configurations of dipoles, moving point charges and current loops are presented for the dynamic spherical multipoles of the electric and magnetic type, whose fields are the vector spherical wave functions (VSWFs). The configurations produce the VSWFs of a specific degree and order in the limit...
