# Effect of the force of two repelling magnets as the distance increases.

Extracts from this document...

Introduction

Effect of the force of two repelling magnets as the distance increases Aim: Our aim is to find out the effect of the force of two repelling magnets as the distance increases. Hypothesis: The Hypothesis is that as the distance between the two magnets increased there would be less force because the magnetic force would weaken. Variables: - What we changed: We changed the distance between the two magnets (cm) - What did we keep the same? We kept the same placement of the magnets, the same balance, and we tried placing the clamp stands at the same level. - What we measured: We measured the force (in g.) of two repelling magnets and also the distance between them. Materials: - 2 Magnets - 1 Ruler (50cm) ...read more.

- We repeated this until more or less 5 cm apart between the two magnets. Diagram: Table of Results: Effect of the force of two repelling magnets as the distance increases Distance from balance (cm) Force between the two magnets (g) 9.8 0 9.1 0.10 8.4 0.24 7.9 0.33 7.4 0.50 6.8 0.76 5.8 1.4 5.2 1.96 4.7 2.76 4.1 4.19 3.4 6.68 2.7 9.67 2.2 15.12 1.7 29.14 Conclusion: Concluding from our results, as the distance between the two repelling magnets increased; there was less force (g) between them due to the weakening between the magnetic force. Comparing the results of the distances between 1.7cm and 9.1, there is a visible force decrease. At 1.7cm apart, the force was 29.14, whilst as the magnets were further apart at 9.1cm the magnetic force was only 0.10g. ...read more.

Conclusion

We started off by placing the clamp stands in the wrong place along with the magnets placement on top of the balance, in the wrong place as well. With the magnet right in the middle of the balances top, and with the clamp far away from it, the readings of our first attempt to do the experiment failed completely, because the readings wouldn't be as accurate. However, as we finally started working on our real experiment, we worked quite well, because we had already figured out about what to do and what not to do. So, we placed the materials in the right place and then all we had to do was start off the experiment. In the end, our experiment did turn out ok, as we got some good results, which showed us what we wanted at first. ...read more.

This then induces the same effect in a neighbouring molecule, creating an instantaneous attraction, giving an instantaneous bond, this effect then travels throughout the molecules. These bonds act as a frictional force as they act against the flow of molecules (resisting the flow).

I wasn't expecting the mass to have any difference on the speed but, even with the light gate, results showed a slight increase. I assume this was due to friction and would like to investigate its properties. Also I would use a trolley than travelled in a straight line!
