Last Week

This last week we are finishing our final report. We still have to do some tables, graphs and the conclusion. The rest of the work has been revised and improved.

Week 23

Today we have completed all of the data that was left. So for the next weeks we can concentrate on the report and organising all of the data in graphs.

These is the table we have completed:

Number of turns	Weight Lifted (g)
	Trial 1	Trial 2	Trial 3	Trial 4	Trial 5	Average (g)
35	2,2355	2,0371	3,2260	1,9832	2,0558	2,30752
30	1,5409	1,7605	2,2666	1,6430	1,8072	1,80364
25	1,3815	1,5048	2,0201	1,4236	1,6319	1,59238
20	1,2645	1,2054	1,7321	1,4532	1,3374	1,39852
15	0,8740	0,8996	1,0468	1,1562	1,0995	1,01522
10	0,5455	0,6275	0,7785	0,9288	0,6816	0,71238
5	0,1175	0,3422	0,5115	0,4598	0,5142	0,38904
1	0,0177	0,0781	0,0638	0,0352	0,0938	0,05772
0	0	0	0	0	0	0

Week 22

This week Guille is working alone because Manu and Carlos have betrayed him and they have gone to Rome the whole week. He will continue on his own collecting more data.

For the next week we will finish obtanining data changing the number of turns of the magnet because the one changing the diameter of the core has been finished today. After obtaining all results, we will process it and create a conclusion.

Week 21

This week, just like the week before, we are collecting data to improve our results.

Week 20

Today we are starting the third evaluation. This evaluation we are going to collect as much data as possible for each of our experiments, so our results can be precise enough. Our objective is to do each experiment at least 5 times.

This week we haven't been able to get results because of the humidity that causes our power supply to overload too fast.

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.

Week 18

Today we continued  obtaining results and we have moved forward do the part of the experiment in which we change the number of coils. This second part of the experiment is going to be done faster because we have already solved the problems we faced at the first experiment. We have used the third screw because is the longest one so we can put a lot of turns in it and by this way, obtaining more data. We managed to finish the magnet with a total of 35 turns (the highest number we expected). So we are ready to finish our experiment the next week.

Week 17

In this week we are continuing with the meausurement of the experiment, after looking closer at the data obtained, we are having trouble being able to identify how the relationship between it´s magnetic power and it´s core are related. 

It seems that some magnets are of different material. Even if they have no noticiable difference at human meausuremnts, having the same color and weight and only changing in it´s electromagneticity.

We have taken the experiment for third time, and the results continue the same way...

Magnets (from smaller to bigger)	Weight (g)	Weight (g)
Manget 1	0,6909	0,7259
Manget 2	0,6388	0,7823
Manget 3	1,1258	0,8400
Manget 4	0,7468	0,7594
Manget 5	0,3763	0,6130
Manget 6	0,3761	0,8931
Manget 7	0,4599	0,9550

Theorethically magnet 3 is the most powerful one, being followed by the fourth. Taken into account that the core gets bigger as the number does, 7 must be much more powerful than 7, but it´s the other way round...
