A circular coil consisting of a number of turns of wire wrapped around a ferrite core, is an example of a simple electromagnetic system. Passing current through the coil causes a circular magnetic flux to be generated within the toroidal core, the direction of which may be predicted using the right hand corkscrew rule or the right hand grip rule. Calculate the magnetic field strength H in a circular coil of mean radius 4 cm, wrapped with 200 turns of wire, if the current flowing through the coil is 0.1 A. For a given coil, the magnetic field strength is directly proportional to the linear current density.

Creationists and scientists have been debating for years about the age of the Earth and the universe. Humphreys does, however, outline his theory of constant magnetic field decay, the dynamic-decay theory. Based upon his assumptions that the energy of the magnetic field has been in a state of constant decay, and taking into account his theory that the Flood caused an accelerated rate of decay that led to a massive energy drop over a relatively short period of time, Humphreys concludes that the earth must only be about 6,000 years old (Humphreys 1993).


The scientific community has been quick to respond to the age data presented by creationists, and they have provided several counters to the claims of Barnes. It is evident that the debate between creationists and scientists will continue for some time, as both sides are bent on proving themselves right. Comparing the maps in Figures 2 and 3 reveals some interesting behavior of the magnetic field. However, this is not a strict rule, as there are features in the Pacific which are moving eastward. Using these time derivatives, the core field can be predicted for the upcoming couple of years. We glossed over the idea that the outer core of the Earth creates the magnetic field and the magnetosphere for the planet.
Researchers in the journal Science have reported that they can now create a cloak that hides objects from static magnetic fields. The team was led by Alvaro Sanchez at the Autonomous University of Barcelona in Spain, working together with experimental scientists at the Slovak Academy of Sciences in Bratislava, and they’re describing a magnetic cloak that could be made inexpensively with readily available materials. The interior of the cloak is lined with turns of tape made from a high-temperature superconductor, which can repel magnetic fields. This cloak is simpler than previous invisibility cloaks, since its permeability is isotropic instead of anisotropic, meaning that it has the same value in all directions.
The overall cost of this cloak was about €1,000 (US $1,000), which is a small amount when it comes to this kind of research. The mean length of the magnetic path (l) is taken to be path through the centre of the circular ring, as shown at the left in the above illustration. It is derived from basic standard units, but is expressed directly in base units and cannot be further reduced.

In this debate, the apparent decay of the Earth's magnetic field has been used by young-Earth creationists as evidence that the world is only thousands of years old, while scientists maintain that the cyclic nature of the magnetic field renders any age produced by magnetic field decay theory to be invalid. Barnes, observed scientific evidence has shown that Earth's magnetic field has not been decaying constantly since the dawn of creation. According to this theory, Earth's magnetic field has been constantly losing about half its energy every 700 years (Humphreys 1993).
Any flaws found in Barnes' work also discredit the work of Humphreys, since Humphreys' work is based upon that of Barnes. The general tendency of magnetic field features to move westward is called the westward drift.
Any magnetic fields enclosed within a superconductor would be undetectable from the outside.
The resulting cloak is less than perfect, but it convincingly demonstrated the raw concept and that it can further be improved using existing materials.
In accounting, it is a standard item in the expense section of a company's income statement.
Careful analysis of both the creationist's and scientist's theories can provide a clearer picture of who is correct in this long-running debate. In fact, the magnetic field has fluctuated and reversed in polarity over time, proven by evidence of periods of increasing and decreasing field energy (Sarfati 1998). Humphreys himself provides no scientific answers to this specific question, instead focusing on his data and theories relating to the time of the Flood, which he denotes as the third millennium before Christ (Humphreys 1993).


Using assumptions that he himself has made about the maximum energy [it is important to note that energy is not the same concept as intensity] of the magnetic field at the time of creation, Humphreys produces the following figure, which shows an age vs. The first point made by scientists is that Barnes used an outdated model in his analysis of the Earth's interior (Matson 2002).
However, X-ray machines and sniffer dogs would probably not be defeated by this kind of cloak. How many people carrying hazardous materials have passed through those so-called “security checks”?
Barnes asserted that Earth's magnetic field has been decaying in a non-cyclic manner at an exponential rate since the beginning of creation (Matson 2002). Due to this cyclic fluctuation, scientists have argued that the strength of the magnetic field cannot be used to determine an age for the earth, since it is a reversible, cyclic process (Stassin 2005).
Elsasser, Earth's magnetic field is generated by a dynamo within the Earth's core (Matson 2002). If they are to prove that Earth is indeed only thousands of years old, they will need to analyze the fluctuations of the magnetic field from a new perspective. If you take a physics course, you'll learn that magnetism and electricity are very closely related. A Hall probe was used to map the magnetic field and researchers discovered that the field lines did not enter the cloak itself.
Barnes used the data of McDonald and Gunst to plot an exponential curve and, by extrapolating the observed data backward into time using his exponential decay equation, Barnes claimed that the magnetic field was approximately 40 percent stronger in 1000 A.D. Second, by using McDonald's and Gunst's data, Barnes only analyzed the dipole component of the magnetic field, which is not an accurate measurement of the overall strength of the Earth's magnetic field (Matson 2002). This dynamo is driven by an unknown energy source, but the subsequent fluid movement within the core generates the magnetic field around the Earth (Matson 2002).
Likewise, scientists will need to continue their research of the dynamo model until the mysterious energy source is identified. The exactness of this cloak which could be made perfect, using currently available materials. I suspect people like GW Bush, Dick Cheney and other mafiosos have very large stakes in those”security companies.
Third, scientists show that the data used by Barnes more easily fits a linear curve than an exponential one, and Barnes chose an exponential curve based on incorrect assumptions (Thompson 1997). Creationists are quick to call this theory into question, because they see the fact that the energy source of the dynamo is unknown as evidence that the theory may be incorrect. If they can discern the source, they will move one step closer to verifying their model; if they cannot identify it, they will need to turn to other models for answers. Continuing this extrapolation, Barnes stated that the Earth must not be older than 10,000 years, or else the strength of the magnetic field would have been so large that it would have melted the Earth (Sarfati 1998).
Russell Humphreys, a nuclear physicist, looks to the Genesis flood as the cause of the fluctuations in the magnetic field.
The answers for both parties lie in continued research - only then will we be able to determine if we are able to date the Earth using its magnetic field as a clock. The magnetic field created in the center of the planet makes your compass point north and protects the Earth from solar winds. Utilizing a creationist theory that the Genesis Flood was caused by the plunging of tectonic plates toward the Earth's core, Dr.
Humphreys claims that the tectonic plates would have caused a sudden cooling of the outer parts of the Earth's core (Sarfati 1998). This sudden cooling would cause convection currents to flow within the core, which would generate numerous reversals of the magnetic field over the course of thousands of years (Humphreys 1993). These field reversals would have happened rapidly at the time of the Flood, according to Humphreys, leading to an increase in the intensity (strength and direction) of the magnetic field until it reached a maximum at the time of Jesus Christ. 1 below, Humphreys believes the intensity of the field has been decreasing since the time of Christ.
