There is few different kind of magnets. Google it, The “rare earth” magnets are man made. The “experts” argue that magnets do not store electricity but have magnetic field. During the process of making a magnet, the manufacture magnetize the raw element with high current and high voltage. It is like charging a battery, but the “experts” still living in deny. Magnets do store energy, but since no one think about retrieving that energy, we have a problem. The “experts” fallow old law about magnetism and will not dare to question that law for fear of losing “reputation”. The only reputation they have is a “shithead” and loser. Just because someone had a “brain fart”, it does not mean that is real. We need to start thinking of magnets as not only magnetic fields (that no one really understand), but energy storage. During the “magnetizing” process of N52 magnet, a 12A and 2400V is apply to small disk – the size of a dime. Tremendous amount of energy in that small piece of metal that no one know the amount of that stored energy. They do not know because they never attempt to measure – why- they fallow outdated teaching. Magnetic field it is energy that expand from center to outwards. The stronger energy is in center and weaken with distance. Sound familiar? – a light, a wave, a sound and go on. It is frequency and the carrier is density. Density, intensity – all the some. Amount of electrons. The higher the number – the more density, but as electrons approach ( and strike) an object, the density getting lower. As the density getting lower, the trawler distance slowly diminish. What is that “magnetic field”?. Positive and Negative electrons reacting to the atmosphere. In picture of “magnetic filed” , the electrons goes from N to S – positive to negative. Since air is piss poor conductor, the discharge will take long time to deplete that “magnetic field”. Why the magnets attract or repel?. The positive side of magnet attract positive electron. When you try to put two magnets with similar polarity, you are trying to compress the positive ( or negative) charge air. Depend of size, and charge of that magnet – you may not be able to push them together. Some of the force will leak on edges. The stronger force will be in the center. Magnets attract a metal ( even the ceramic magnet are made of metal) because they are made of metal and electrons attempt to equalize the amount of electrons. Everything need to be balance. Solid magnet and copper wire – if you move magnet near a copper coil, the electrons will be forced to jump to that wire to equalize (balance) the amount of positive and negative electrons in that wire. If you do not move the magnet, the electrons will jump until the amount is balanced. Any movement disturb balance in air and movement attempt to regain the balance. All instruments consume the density and that is how you know of electrons flow. The faster you move the magnet, the more disturbance, force the electrons to jump to a wire and the meter consume more energy. With time, you will deplete that magnet.
