The Application of Magnetism and Electricity How can I use the concepts of magnetism and electricity to create energy?

Objective: To discover the full potential of electromagnetism and electricity in order to create energy.

Article 1: Electromagnetic Energy (http://www.wisegeek.org/what-is-electromagnetic-energy.htm)

- Photons control the aspects of electromagnetic energy. Interestingly, the shorter the wavelength, the higher the frequency. Photons are the particles that carry the electromagnetic force, and the interactions of electrically charged objects are explained in terms of the production and absorption of these particles, which themselves carry no charge. Modern technology like the Internet depend heavily on radio waves and on light channeled through fiber optic cables. Laser technology uses light to read from and write to CDs and DVDs. Most of what scientists know about the universe comes from the analysis of EMR of various wavelengths from distant stars and galaxies.

- The Sun excretes electromagnetic energy that can be harnessed using solar panels. If in some way that we can convert radiation, which is also a form of a wave, then we can gather a lot of energy radioactive materials instead of damaging us instead.

Video: "Electromagnetic Motor" 17th March 2017

This is one of the possible application of electromagnetic energy. It uses materials commonly found in motors. While searching for videos about electromagnetic energy, I encountered videos called " Free energy" motors in relation to this kind of generators. After conducting further research about this kind of motors, I learned that the mechanism it uses is called perpetual motion. The reason why perpetual motion motors are not efficient because of Magnetic hysteresis and Magnetic damping. My future research would probably concentrate on creating an efficient electromagnetic motor while addressing magnetic hysteresis and magnetic damping.

4/21/17 Electromagnetic Induction

While researching about how magnets exactly create energy, I have stumbled upon electromagnetic induction. Electromagnetic induction is a process where a conductor is placed in a changing magnetic field, causing the production of a voltage actoss the conductor. The process of electromagnetic induction causes an electrical current. Michael Faraday, the discoverer of electromagnetic induction, studied magnetism and electricity in order to laid the foundation of the principle of electromagnetic induction. He also saw the relationship between chemistry and electromagnetism, also known as electrochemistry. Interestingly, the topic I have been searching for know brought light to the fact that two of the topics I am interested the most in terms of energy (chemistry and magnetism) would come to this point of electromagnetic induction.

4/24/17 Uses of Electromagnetic Induction

According to Splung.com Physics, an application of magnetic induction is a transformer. With this knowledge, I might see if I can incorporate magnetism in a transformer.

According to quora, it can also be used for a transformer to “allow the more efficient use of AC power by boosting the voltage and thus decreasing the needed current and hence resistive power losses to deliver a given amount of power, rely on mutual induction between two coils, the primary (input) and secondary (output)”

Interestingly, magnetic induction is in relation to levitation, which is also my primary interest in magnetism. I will further research between a transformer and levitation. At the moment, I am unsure on what to use these principles; however, I plan to make an electric generator.

Notes:

I. Transformers help achieve better transmission efficiency while transferring the power over longer distances.

II. The basic working principle of a transformer is electromagnetic induction.

III. According to this principle, a varying magnetic flux associated in a loop will induce an electromotive force across it * easily produced by a coil- alternating EMF system.

IV. Fluctuating magnetic field will induce an EMF in the secondary coils due to electromagnetic induction.

V. EMF per turn for both the primary and secondary coils be the same

VI. Relationship between primary and secondary coils: EsIs=EpIp

VII. Transformers with high power ratings generally employ with a special kind of winding known as a disc type winding- where separate disk windings are connected in series through outer and inner crossovers.

VII. Delta configuration and Star Configuration.

VII. The purpose of thin laminations is to reduce energy lost due to eddy current formation,

VIII. Energy Losses that happen in the Transformer: Eddy current loss, hysteresis loss, I2R loss.- All are dissipated as heat

4/27/2017 Reflection

The video enlightened me about the concepts of a transformer and how it works with electromagnetic induction, which is an in-between electricity and magnetism. With this knowledge in store, I think I might be able to see how I can use this in the field of aviation. I did a quick research and I found out something called Transformer Rectifier Unit (TRU). This might be my primary research focus in the next Passion Project, if I head to the aviation-focused path.

5/5/27 A Universal Wireless Charger? How does Wireless charging work?

*wireless charging uses a loop of coiled wires around a bar magnet — which is known as an inductor.

* Electromagnetic field can be used to transfer a voltage, or charge.

*The amount of electric charge transferred is proportional to the number of coils that can be looped around the tiny bar magnet, as well as the strength of the magnet.

* EMFs are produced by such things as power lines, electric appliances, radio waves, and microwaves.

SOURCE: https://www.quora.com/Do-mobile-phones-emit-harmful-radiation-or-electromagnetic-fields

*The first one is easy, cellular frequencies vary between 450–2000MHz, but 800 or 900 MHz

* Calls, Bluetooth, and any wireless action by the phone increases the amount of electromagnetic field/radiation.

Reflection: Although my research has no relation to my supposed primary focus on my last reflection, I believe that this research would also help one of my key interest: Charging. By finding the electromagnetic field emitted by phones, I can use that to make a device that would correspond to said electromagnetic field in order to charge the device. In the our current world, our lives are almost always powered by some electrical device. Without charge, these devices would not function well. If there was some universal charger that could charge any device without connection, which I plan to create sketch-wise, then It would make peoples' lives easier. Something people that thought was harmful would become useful and benefit our lives.

Essentially, the video below demonstrates what I want to use my research. It is one of the inventions I would like to work on.

May 17th, 2017 Extracting Energy from Electromagnetic fields.

Source: https://arxiv.org/pdf/1208.1702v2.pdf

"We use the theoretical results to present a surprising result which for the best of our knowledge is new: a machine that can extract energy from an external magnetic field. Under appropriate conditions (µε >1) in motion will start increasing the electromagnetic angular momentum stocked in the electromagnetic field in the direction contrary to the original mechanical angular momentum of the device which thus will start increasing (theoretically)"

A paper from Cornell University states that it is theoretically possible to extract a huge amount of energy from external magnetic fields using an unfamiliar formula I am unaware of. This shows that it is a possible thing, and I would like to do it in a small scale.
