There are two different theories about how the core makes the energy for the magnetic fields that we have.
1.) The dynamo theory: This is the theory that the core makes the magnetic fields that we have by the cores outer fluids, temperature of the core and the rotation of the earth mixing together charging electrical currents, which forms our magnetic fields. This theory like the Raid Decay theory theory believes that the cores magnetic field will change its direction over time, which will weekin the magnetic field but the dynamo theory believes it differently. they believe that the earths magnetic direction will happen slowly because it takes time for the temperature difference in the core to change the rotation of the cores outer fluids. There estimation of the magnetic change is in 2000 years, but in 1989 scientists have found evidence that the earth has changed its direction in 15 days the very opposite of how long there time range is.
2.) The rapid decay theory: This is the theory that the cores electrical currents are a result of its creation . It is actually possible to calculate the amount of energy in the core with this theory. As a result that electrical current would slow down over time due to its creation. Studies have shown that over time the cores energy has decreased by five percent each century. This would be true because matter resists all electrical flow, which would slow down the electrical currents of of the core . Another thing is that would prove that the magnetic field is decreasing is that scientists have found that the earth has turned around in the direction of its circular motion. This means that the earths magnetic field has pointed somewhere in the opposite direction of were of were the magnetic field is now. You may be wondering how do we know this. There are certain materials in the crust that have a magnetic pull toward the magnetic field like a compass. And the natural magnetic rocks that are in the crust are pointing in the opposite direction. That means that the earths rotation has changed. This theory also has correctly calculated the magnetic field of every planet that has one. For example the dynamo theory says that mars has a magnetic field, but the rapid decay theory says that mars had one but not any more.Another thing was that the rapid decay theory along with the dynamo theory all had an estimations of the magnetic field of each planet that the Voyager traveled to. The dynamo theory was off by a factor of 100,000.
I think that the rapid decay theory is the theory to place your money on because look at all the evidence that it has given us. There's just no scientific way you can back up the dynamo theory. They have no proof to back there theory up and it never has given us any calculations of the magnetic fields on other planets unlike the Rapid Decay theory.

Ion and Socrates
I recently read a conversation about Ion and Socrates. In this conversation they talked about the arts. Now Ion was a reciter for Homer. He thought himself to be the best reciter in the world and that his gift came from within himself. But Socrates asked him do you recite other piotes. He replied no. So Socrates asked why is this for all the other poites right about the same things do they not. Ion replied that what he said was true, but all the other poites bore him and are not as good as Homer. So Socrates asked him If you are the best reciter in the world surly your inner ability to recite should unable you to credit them to. I think not Ion replied. Well then your ability to right these things is not from you,but from God. And God has inspired Homer with his talents to reflect truths. And you get your inspiration to credit Homer for these things from God. In the end Ion was humbled to find this was true. I think we as people need to realize that these amazing talents of ours are sent from God and we need to use them to reflect God and the truths of God.

socrates

and wrong this is also part of our human nature. Though some say that they do not believe in right and wrong there is only reason and understanding. But they have
contradicted this theory because sometime in their life they have had a curial with someone over something, and the point of a curial is to show that some body is in the wrong. It is just part of our human nature to do so,but over time people have changed the direction of that nature. For instance the great writings of Plutarch he had spoken about how Cesar was walking through the great roman palace and noticed some people walking by with little dogs and cats in there arms. They were loving these animals as if they were their own children. He was troubled by this for they had taking that natural tendency to love and pour affection upon a person, and had directed that instinct to something unworthy of this affection.Socrates was a man who fought for the understanding that we as humans have strayed from the way we should direct our true human nature. He believed that we had taking our natural instincts and used them the wrong way. Like gay marriage, we as men were meant to love women, but some men have taken there natural feeling to love a woman and turned it around and now they love other men. So he fought to defend the true human nature along with many many other things. He also showed how the ugly, like himself were truly beautiful. He would say things like" Some people think my nose is ugly because it flares out, But because it flares out I can smell much better than most people can So it is truly beautiful." He spent all of his life tyring to defend this true human nature.But in the end because of the fall of Athens the people needed Someone to blame for this, so they blamed him. He was caught and sentenced to death by poising. He was truly a man of his convictions, because at his trial instead of tyring to defend himself he criticized the people in power. This did not help anything at all. So he was sentenced to death as I have said. If he could do this for the sake of reason and understanding than we can surly do the same for our faith.
