I. Research Question
How did the amount of volt affect the strength of the electromagnets?
Reason
I wanted to know if an electromagnet can be strengthen even more through the increase of its energy.
II. Introduction:
What is electromagnet?
Electromagnet is a magnet that runs on electricity. Electromagnet is created when a copper wire is wrapped around a nail and is connected with batteries, which will gives the electric needed to make the nail into a magnet. There are factors that affect the strength of the electromagnet such as the strength of the magnet depends on the amount of …show more content…
Types of paperclip
Description
There are different types of paperclip that comes in different size and types making it heavier or lighter, the lighter it is the easier it will attach. While the heavier it is the harder it will attach. By using the same type all the paperclips will have the same mass and shape making the electric the only factor that decides on how many paperclips will attach.
Number of coils
Description
Using the same number of coil means that the nail will won’t receive extra or less voltage as the number of coil determines the rate of volt given to the nail. We believe that as long as the electricity flowing from the battery is moving circularly it will produce electromagnetic as it creates magnetic domain where the electron aligns and with more than 10 coiling, it wouldn’t produce a difference of electricity.

The experiment itself had a huge error in the second and first trial as we did not follow the procedure well. But this is also causes by the lack of time, we are forced and pressurize in that condition where are our experiment is not working. So we rush the work starting at a battery amount of 2, which can cause a sudden change to the nail magnetic domain. The lack of measurement is also a problem as we did not count the amount of volt in the battery and instead follow the amount of volt listed, which can be inaccurate as the battery is not new and may had been use in any other experiment
