Week 19

This week we have finished the second part of our experiment. The results of this second part made sense from the beggining so we can determine clearly that the number of coils affects the power of the magnet.
In order to make the experiment more reliable and not changing of nucleus, we started bu the biggest number of turns (35) and after meausuring how much wight it could lift, we cutted 5 coils and continued. When we had 5 turns, we proceded with 1 (which had a ridiculous amount of force) and with none, which, as expected, didn´t lift any weight.

35 turns
2.2355g
30 turns
1.5409g
25 turns
1,3815g
20 turns
1,2645g
15 turns
0,8740g
10 turns
0,5455g
5 turns
0,1175g
1 turn
0,0177g
0 turns
0g

At the final stage of the experiment (when the magnet had less than 15 turns), the power supply overloaded because the current was increasing because of the high temperature of the system. However we were able to proceed because it overloaded after 3 sec, so we had to be fast, but it didn´t affected the experiment (leaving apart the fact that we had to repeated several times).
With this, our experiment is finished and ready to analyse.
