Week 3 : Testing and trying

Week 3

                       Hi all , it's week 3 . During this week , we will be trying to construct and setup the experiment . On the other hand , we will be also carry out testing on the magnetic strength for the magnets we bought . 

         With the raw materials bought , let's try to set up our experiment !

                         Beside that , special thanks to Dr.Woon for giving us his speaker and let us to carry out material extraction so that we can try for another magnets . 

                        At the same time , we trying to set up our experiment in different ways in order to explore the difference in the reaction of  magnets toward the solenoid .

                        Not only that, we also manage find a software which call as autotracker to track the motion of the magnetic pendulum. Here is the link to get the software (https://physlets.org/tracker/installers/installer_help.html). 

                                                          

    

WHAT HAVE WE LEARNED?

                   From the testing on experiment that we carried out, we get to know that we need to find the magnetic ball or in other words , a magnet in sphere shaped because other shape of magnet will cause the complex motion and it is hard to track the motion according to suggestions by Dr. Woon. Beside that, we also learnt that in order to have a ideal simple harmonic motion, the angle of pendulum should not exceed 5 degree and the mass of pendulum must be larger than the string significantly. Based on the  explanation by Dr. Woon, we know that the copper wire that use to make the solenoid must coated with the insulator to avoid the current pass through. Lastly, we found out that we still not familiar with the autotracker software ,  therefore we will work hard and try our best to master the autotracker software , at the same time also will try our best to find a magnetic ball or "make" the magnets in to sphere shape .     

                Feeling interested in our project? No worries ,we will be updating our progress weekly so don't forget to catch up our updates ya . See you guys soon!
