First all we like to thank God for guiding us every time we have meetings and trials of our experiment. We would like to express our deepest gratitude to all those who gave us the possibility to complete this investigatory project. Our sincere thanks to all the people who have contributed to and worked for this. Especially to our parents who are always supporting us in all we do. We also would like to give thank to our Physics Teacher, Sir Lemuel F. Valdez for encouraging, inspiring and giving pointers to improve and to finish this project. We also would like to give thanks to Ms. Shiela Mae Hisugan of First Year Planning for providing us the magnet we needed for the experiment and to Mar-Leo Trading for providing the materials that we used. And lastly we would like to give thanks to Mrs. Analyn Saturnino for the snacks that we ate every time we had our group discussion.


Title: Electromagnet (Simple features and uses)

No. of Pages: 9

This investigatory project aims to illustrate how to make an electromagnet. It also aims to illustrate the simple features and uses of a basic sample of a electromagnet. This study wants to show the relationship between electricity and magnet. In this study we want to show that the electric current passes through the coil round around the screw, it creates a magnetic field that reaches out in expanding circles. When wire carrying electricity is twisted into a coil. The magnetic field twists with the coiled wire, causing the magnetic field lines to concentrate inside the coil. This creates a powerful magnetic effect inside the coil.

Chapter 1


An electromagnet is formed when a current carrying wire is wrapped around an iron core. The strength of the electromagnet depends on, among other things, the number of times the wire is wrapped around the core and the amount of current that is flowing through the wire. The Electromagnet Experiment Stand is a device that demonstrates the relationship between the strength of an electromagnet and the number of coils wrapped around its core as well as the relationship between the strength of an electromagnet and the amount of current flowing through its coils.

Scope and Delimitation

This investigatory project focuses mainly on the following:

Relationship of electricity and magnetism.
The electromagnet itself.
Purpose of the electromagnet.
The solenoid.

Statement of the Problem

What is the purpose of electromagnet?
How can we make an electromagnet?

Definition of Terms

Magnet - Middle English magnete, from Anglo-French, from Latin magnet-, magnes, from Greekmagnēs (lithos), literally, stone of Magnesia, ancient city in Asia Minor. Electromagnet - A core of magnetic material (as iron) surrounded by a coil of wire through which an electric current is passed to magnetize the core. Electromagnetism - Magnetism developed by a current of electricity. A fundamental physical force that is responsible for interactions between charged particles which occur because of their charge and for the emission and absorption of photons, that is about a hundredth the strength of the strong force, and that extends over infinite distances but is dominant over atomic and molecular distances —called also electromagnetic force.  Coil...
