Displacement current: examples that go beyond the beaten path
Álvaro Suárez, Martín Monteiro, Arturo C. Martí
The Ampere-Maxwell's law and the displacement current constitute one of the most difficult aspects of electromagnetic theory for students in introductory electromagnetics courses.…
How far away is infinity? An electromagnetic exercise to develop intuition regarding models
Alvaro Suarez, Martin Monteiro, Mateo Dutra +1
The estimation of the electric field in simple situations provides an opportunity to develop intuition about the models used in physics. We propose an activity aimed at university…
Bernoulli's muddle: a research on students' misconceptions in fluid dynamics
Alvaro Suarez, Mateo Dutra, Martin Monteiro +1
Bernoulli's equation, which relates the pressure of an ideal fluid in motion with its velocity and height under certain conditions, is a central topic in General Physics courses fo…
Normal coordinates in a system of coupled oscillators and influence of the masses of the springs
Alvaro Suarez, Daniel Baccino, Martin Monteiro +1
Experimental analysis of the motion in a system of two coupled oscillators with arbitrary initial conditions was performed and the normal coordinates were obtained directly. The sy…
An experiment to address conceptual difficulties in slipping and rolling problems
Alvaro Suárez, Daniel Baccino, Arturo C. Marti
A bicycle wheel that was initially spinning freely was placed in contact with a rough surface and a digital film was made of its motion. Using Tracker software for video analysis,…
Using the Euler method in a spreadsheet to study a nonlinear oscillator
Alvaro Suarez, Fernando Tornaria
The one-dimensional nonlinear oscillations of a magnet attached to a spring and interacting with a set of magnets are analyzed theoretically and experimentally. The equation of mot…
