Electromagnetism
Lab Worksheet
1. Explain what it means when we say a substance is magnetic.
It means that the substance has a lot of electrons that are creating magnetic fields.

2. Discuss the relationship between electric and magnetic fields.
An electromagnetic wave generates both, electric and magnetic fields. A magnetic field can be induced by a wire conducting an electric current and a electric field can be induced in a coiled piece of copper wire if a magnet is moved through the center of the coiled wire.

3. Before you begin your lab, you need to form a hypothesis that reflects which material, voltage, and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement.
I think the material that will produce the strongest electromagnet will be copper because it is a very good conductor, the voltage that will produce the strongest electromagnet will be 100 volt because it will have a lot of power and the number of winds that will produce the strongest electromagnet will be 100 because I think if there is more of the material it will have more power.

4. Record your data for each trial.
I attached the photo of the chart.

The experiment proved my hypothesis, because when I tried to do the experiment with different materials than copper and different voltages than 100 and different number of winds than 100, the result would always be less paperclips.

2. 6. What role does voltage play in the formation or use of an electromagnet? 3. The voltage plays and important role because it is the power that the electromagnet needs to be able to work, the more power the more work, so the electromagnet would work better with a lot of voltage.

1. 7. If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet? 2. The possible uses for the electromagnet

The invention of electricity has benefited mankind in several aspects of life ever since the 1800s. Over the course of the past two centuries, scientists have been developing theories that serve as the backbone for various devices today. Such intellectuals have been attempting to understand the credibility and applicability of the already existent theories, such as electricity and magnetism. In addition, they have introduced new concepts by either creating them from scratch, or combining other theories. Electricity, for instance, is a form of energy fueled by the movement of charged particles, called electrons. It is an electrical current if these electrons flow from high to low voltage. If the charged…

A DC electromagnetic generator produces direct power and also, electrical power (just like the AC generator). It is also produced based on same fundamental principle of Faraday’s Law of Electromagnetic induction where whenever a conductor cuts magnetic flux, dynamically induced electromotive force is produced, and this causes current to flow if the conductor/conductors is closed. The direction of induced current is given by Fleming’s right hand rule.…

An electric field surrounds all electrically charged particles. With electric fields, one can determine the effects of all of the charges in the environment. In this lab entitled “Electric Fields and Potential Mapping”, the main goal obtained was to examine and deliberate the effects of an electric field and electric potential. Examples of some effects of electric fields include resultant forces, changes in motion, changes in current flow, etc. By using conductive paper connected to a power supply and a voltage probe, an observation of the effects of an electric field could be carried out in a more tangible setting.…

Aristotle attributed the first of what could be called a scientific discussion on magnetism to Thales of Miletus, who lived from about 625 BC to about 545 BC.[1] Around the same time, in ancient India, the Indian surgeon, Sushruta, was the first to make use of the magnet for surgical purposes.[2] There is some evidence that the first use of magnetic materials for its properties predates this, J. B. Carlson suggests that the Olmec might have used hematite as a magnet earlier than 1000BC[3] [4]…
