A. Statement of the Problem/ Objectives:

The following are some objectives or what the proponents would like to carry out in the progress of this project:

To be able to make an electromagnet in the simplest way.

To be able to relate the number of turns of wire with the strength of the electromagnet

To be able to attract as many paper clips as possible.

To be able to explain and recognize the principles and concepts behind electromagnetism.

B. Materials and Methods:

I. Materials:

These are some of the materials used by the proponents in making the electromagnet:

One iron nail

Stranded copper wire

One or more D-cell batteries

Scissors

Paper clips

II. Methods:

These are what the proponents did in making the electromagnet:

The proponents first gathered all the materials needed for the making of the electromagnet. The next thing that the proponents did was to remove some insulation. So a pair of scissor or a cutter was used in order to remove the insulating rubber starting from each end of the wire to expose the copper wire. The wire was wrapped around the nail in a spiral manner. The proponents left enough of the wire unwound so that it can be attached to the battery. The wire was wrapped only in one direction, but with many layers. The group attached using their hands one end of the wire to the positive terminal of the battery and the other end of the wire to the negative terminal of the battery. Then, they used their hands was again used to hold the ends of the wire attached to the batteries. Lastly, they tested their newly made electromagnet.

D. Theoretical Framework:

In 1820, Danish scientist Hans Christian Oesterd (1777-1851) had a stoke of luck while performing an electrical experiment. Oesterd had a compass on his bench near a wire that was connected to a battery. He noticed that when the electric current was switched on, the compass needle moved. He realized that the current flowing through the wire was producing a magnetic effect. This was the discovery of electromagnetism, the related effects of electricity and magnetism. Electric currents have magnetic effects, and magnetic fields can produce electric currents.

An electromagnet is a magnet ...

#### Here's what a star student thought of this essay

Presented well in different clear subheadings. Grammar, spelling and punctuation are all to a good level.

The group includes pictures of the different materials so the reader can gain an idea of what the magnets may be like. The method is clear to read but to make it easier to read and follow it should have been presented in bullet point form with clearer instructions on how to strip and connect the wire. It would have been helpful to include a diagram of stages here. The science behind the electromagnet is explained well. The different experiments used seemed a bit random and the results were not well documented. The theory behind each change was only slightly explained and should be explained a bit more thoroughly such as to include exactly why they gained the decision for each change. For example, why did they use thinner and longer copper wire, what was the reasoning behind it. The conclusion is adequate and improvements are suggested but again the reasoning behind it is not very well explained.

A group piece of coursework. Response to the aim was done quite well but as they achieved all their aims through the experiment, but I'm not sure they recognised all the principles behind electromagnetism so should look at this more thoroughly in their own time as some of their explanations were not explained very well in relation to the scientific evidence.
