A smartphone-based simple method for determination of the free space permeability
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
A simple and novel method is designed to determine the free space permeability. This value is computed from the expression of the terminal velocity of a magnet falling through a co…
Determination of the acceleration due to gravity by studying magnet s motion through a conducting pipe
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
We determine the acceleration due to gravity (g) in a novel way using a magnetic sensor and video analysis technique of a smartphone. The same applications are used to measure the…
Study of the effect of electromagnetic damping force on a magnet oscillating near a non-ferromagnetic conducting plate
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee +1
We have designed an experiment that involves studying the effects of a conducting plate on the motion of an oscillating disc magnet. We have employed the video analysis method by T…
Smartphone-based measurement of magnetic force and demonstration of Newton third law of motion
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
A fascinating approach to teaching Newton's Third Law using readily available technology is presented in this article. Magnetic forces are measured by using a smartphone's pressure…
LiDAR based determination of spring constant using smartphones
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
A novel use of the LiDAR sensor of a smartphone in introductory physics experiments is discussed in this article. We have determined the spring constant for various combinations of…
Determination of the magnetic moment of a magnet by letting it fall through a conducting pipe
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
A novel method is proposed to determine the magnetic moment of a magnet by studying its free-falling motion inside a non-ferromagnetic and conducting pipe. The dynamics of a neodym…
