Wiener, Gerfried J.; Woithe, Julia; Brown, Alexander; Jende, Konrad – Physics Education, 2016
In the context of the recent re-start of CERN's Large Hadron Collider (LHC) and the challenge presented by unidentified falling objects (UFOs), we seek to facilitate the introduction of high energy physics in the classroom. Therefore, this paper provides an overview of the LHC and its operation, highlighting existing education resources, and…

Koudelkova, Vera – Physics Education, 2016
A new simple arrangement how to demonstrate diamagnetic levitation is presented. It uses pencil lead levitating in a track built from neodymium magnets. This arrangement can also be used as a classroom experiment.

Nunn, John – Physics Education, 2014
A simple inductive gravimeter constructed from a rigid plastic pipe and insulated copper wire is described. When a magnet is dropped through the vertically mounted pipe it induces small alternating voltages. These small signals are fed to the microphone input of a typical computer and sampled at a typical rate of 44.1 kHz using a custom computer…

Onorato, Pasquale; De Ambrosis, Anna – Physics Education, 2013
We present a sequence of activities aimed at promoting both learning about magnetic forces and students' reflection about the conceptual bridge between magnetic forces on a moving charge and on a current-carrying wire in a magnetic field. The activity sequence, designed for students in high school or on introductory physics courses, has been…

Quinn, Terry; Quinn, Lucas; Davis, Richard – Physics Education, 2013
A watt balance is an electromechanical device that allows a mass to be determined in terms of measurable electrical and mechanical quantities, themselves traceable to the fundamental constants of physics. International plans are well advanced to redefine the unit of mass, the kilogram, in terms of a fixed numerical value for the Planck constant. A…

Straulino, S.; Orlando, A. – Physics Education, 2012
The basic theory of radio broadcasting is discussed from an experimental point of view. First, concepts like wave modulation and tuning are explained with the use of instruments in the physics laboratory. Then, a very basic radio receiver is described and assembled, whose most important feature, like in the old "crystal radios", is the absence of…

Abdul-Razzaq, W.; Bushey, R.; Winn, G. – Physics Education, 2011
Physics is essential for students who want to succeed in science and engineering. Excitement and interest in the content matter contribute to enhancing this success. We have developed a laboratory experiment that takes advantage of microwave ovens to demonstrate important physical concepts and increase interest in physics. This experiment…

Gagnon, Michel – Physics Education, 2011
Mainly used in the 1960s, bubble chambers played a major role in particle physics. Now replaced with modern electronic detectors, we believe they remain an important didactic tool to introduce particle physics as they provide visual, appealing and insightful pictures. Sadly, this rare type of detector is mostly accessible through open-door events…

Chittasirinuwat, O.; Kruatong, T.; Paosawatyanyong, B. – Physics Education, 2011
The magnetic gun was chosen as a hands-on activity for our high school students. When conducting this activity in the classroom, we found some interesting points were raised following difficulties encountered by the students. Some students proposed that during the collision, the magnet changed its pole then it pushed the last ball out of the…

Bonanno, A.; Bozzo, G.; Camarca, M.; Sapia, P. – Physics Education, 2011
In this article we describe an experimental learning path about electromagnetic induction which uses an Atwood machine where one of the two hanging bodies is a cylindrical magnet falling through a plexiglass guide, surrounded either by a coil or by a copper pipe. The first configuration (magnet falling across a coil) allows students to…

Gallitto, Aurelio Agliolo – Physics Education, 2010
The event "School adopts an experiment" is an event targeted at high schools and secondary schools. It is based on a tight and direct collaboration between researchers and school students and teachers. Several schools were involved in the event by "adopting" an experiment in physics research laboratories. Groups of selected students were first…

Wang, Xia-Wei – Physics Education, 2010
Employing Bohr's quantum theory, the author deduces three limits, which correspond to the magnetic fields of white dwarfs, neutron stars and the strongest in the universe. The author discusses the possible origins of magnetic fields due to collapse of stars, which produces a magnetic field of 10[superscript 8] T. Although the complete analysis…

Becker, M.; Koblischka, M. R.; Hartmann, U. – Physics Education, 2010
We show the construction of a so-called levitation balance which is capable of measuring the levitation forces between a permanent magnet and a superconducting high-T[subscript c] thin film sample. The underlying theoretical basis is discussed in detail. The experiment is performed as an introductory physics experiment for school students as well…

Ng, Pun-hon; Wong, Siu-ling; Mak, Se-yuen – Physics Education, 2009
In this article, we describe a simple method which can be used to measure the efficiency of a low power dc motor, a motor-converted dynamo and a coupled motor-dynamo module as a function of the speed of rotation. The result can also be used to verify Faraday's law of electromagnetic induction. (Contains 1 table and 8 figures.)
