Electromagnetic induction one of the most important concept around which most of the devices are developed around. My investigation explores the same concepts wherein a magnet falling through a copper tube depicts the same concept using a theoretical and experimental model. To be precise the research question is to investigation how the thickness of the copper tube affect the time taken for the magnet to fall through it. The investigation was done by dropping a magnet inside the copper tubes of different thickness and the time taken by the magnet to pass through the pipe of one meter length was noted. Moreover a theoretical model is devised using some concepts and equations. Using the theory the actual value of the gradient i.e. 1 ν /w was found to be 120.58 m-2 s. in the investigation, the value of the gradient was found to be 116.89 m-2 s, which is only deferring by 3.16 % form the actual value. Therefore the investigation is accurate and reliable. Also the relationship between the thickness of the copper tube and the time taken by the magnet to pass through it is found to be linear, whereas the thickness increases the time taken by the magnet also increases.
