Combining Physics and Mathematics Learning: A Taylor Series Analysis of an Oscillating Magnetic Field
Santiago Ortuno-Molina, Adrian Garmendia-Martinez, Pedro Fernandez-de-Cordoba +3
In this work, we present a simple and low-cost experiment designed to study the oscillations of the magnetic field created by a cylindrical magnet under two different conditions: f…
Using a remote control to determine the infrared absorption coefficient in water
Santiago Ortuno-Molina, Adrian Garmendia-Martinez, Francisco M. Munoz-Perez +2
In this work, we present a simple and low cost experiment designed to determine the infrared water absorption coefficient. We used a TV remote control as a point source of infrared…
A very low-current electromagnetic induction experiment enhanced by acoustic means
Santiago Ortuno-Molina, Rod Milbrandt, Juan C. Castro-Palacio +1
We have created a simple, portable, low-cost setup allowing the students and teachers to experiment with and discuss electromagnetic induction in a safe way, using low currents. Th…
Visualizing beat phenomenon between two amplitude-modulated (AM) light beams on a solar cell using smartphones
Santiago Ortuno-Molina, Francisco M. Munoz-Perez, Juan C. Castro-Palacio +1
We present a new simple experimental setup for demonstrating beat phenomenon. We have combined two amplitude-modulated light beams on a solar cell using two smartphones as signal g…
