Q: What materials affect the attraction of magnets?: There are a few materials which are naturally magnetic, and have the potential to be turned into magnets. Some of these materials are iron hematite magnetite ionized gases (such as the material stars are made of) A magnet can be made to stick to objects which contain magnetic material such as iron, even if they are not magnets. But a magnet cannot be made to stick to materials which are plastic, or cotton, or any other material, such as silicate rock, which is not magnetic. Just because a material contains iron or some other magnetic material, however, it may not be a magnet. It takes special conditions to turn magnetic material into magnets. That is because a magnet is an object from which the force of magnetism originates.

Q: For example, if you were to put a magnet on either side of the material, the magnets wouldn‘t try to pull together.: Any superconductor is perfectly diamagnetic and therefore has no magnetic field inside it. A large enough superconductor would prevent two magnets from attracting or repelling each other.

Q: The permeability of magnetic material is high or low?: If it is to pay attention to permeability, then it should be soft magnetic material. In general this material can be divided into soft magnetic materials and magnetic materials. The difference between the two is the magnitude of the coercivity, which can be interpreted as the magnitude of the applied magnetic field which must be applied to the disappearance of the magnetic force.

Q: Computers can store Information, and wipe it for what must be like forever. but I don‘t understand, information has to be stored on something physical, wouldn‘t that physical storage device become brittle over time?: All information is stored on your hard drive. Your operating system, your information, music, pictures, videos, documents etc. All of it is binary code(0's and 1's separated magnetically), basically there is a binary code for all characters on your keyboard, this will translate ultimately into programs you and I can understand. So if you want a letter a or A you have to have the binary code to represent the letter, so the same thing applies if you want a space, etc Of course along the line this code become commands and sooner you know you can open files, programs and finally point to links to open your digital media. You are right after a while your hard drive is bound to give up and by that I mean stop working. All devices with moving parts or electrical(usb external memory) sooner or later have to brake down. My best recommendation is that you save your precious information on dvds, the reason is that a dvd holds just about 5 times more information than a cd.

Q: What Is Magnetic Attraction Filtration If Possible Could You Give Me An ExampleThanxx]: Magnetic Attraction: attraction for iron; associated with electric currents as well as magnets; characterized by fields of force and an example of magnetic filtration is some filters in engines use a small magnetic pad to on the outside of the oil filters to attract the metals in Diesel or Gas through the filter to keep the engine clean and free of debris.

Q: Can you simply define the terms magnetic Induction, magnetic intensity, and magnetic permeability?: Simple answers: Magnetic Induction is the fact that a changing electric field can make an object magnetic. Magnetic Intensity indicates how strong the force of magnetism is. Magnetic Permeability represents how much a given material will become magnetized. An object like an iron nail will have a permeability 1000 times greater than a non-metal item.

Q: 1) Suppose you have 2 bars, one is a permanent magnetic, the other is not a magnet but is made from a ferromagnetic material like iron. The 2 bars look exactly alike. By using another magnet bar, how can u determine which one is permanent magnetic, which one is not.Can you determine the identities of the look-alike bar with the aid of a 3rd bar that is not a magnet, but is made from a ferromagnetic material? Give reasons!2) In a TV commercial that advertises a soda pop, a strong magnetic pick up the delivery truck carrying cans of the soft drink. The pictures switch to the interior of the truck, where cans are seen to fly upward and stick to the roof just beneath the electromagnet. Are these cans made entirely of aluminum? Justify your answer.: The vast majority of Christians do not, indeed, read the bible. They merely follow what their pastor preaches from the pulpit. And therein lies the whole problem. They wind up hating everyone and become discontented. Some pastors, like Fred up in Kansas are really into hate. While others (Ted Haggard, Jimmy Swaggart, Jim Bakker, etc.) are more into hypocrisy. But the result is the same.

Q: I would like a homemade magnetic board I can hang for my kids in their bedroom to put magnets and photos and toys and natural magnets. Not from walmart (too lightweight and dont think strong enough) Are there any geologists or metal workers who know about this stuff? The kids would love something like that. Thanks !!: Limestone (or other carbonate rock) bedrock caverns disappearing streams springs sinkholes collapsed cavern ceilings

Q: My A-level book doesn‘t cover this, and while it‘s not included in the syllabus, i‘d really like to know:1- What causes unlike particles to attract and vice verse?2- Why do magnets exist only as dipoles?3- What would be the significance of finding a magnetic monopole?4- What exactly makes up a magnet? (Particle wise)5- What causes magnets to attract some materials more strongly than others? (if at all)?6- Why is gravity weaker than all the other forces?: Unfortunately you can never receive a real answer to these questions. It is just the way our fundamental forces work. There might be a fundamental control panel of our universe in which an extraphysical being can tune all of these observations to being different. If you could thouroghly answer all these questions, you are likely eligible for a Nobel prize. 1- What causes unlike particles to attract and vice verse? We don't know why. This is just the way the force of electrostatics works. 2- Why do magnets exist only as dipoles? Because the source of all magnetism is charges in motion, and all charges in motion create complete loop fields. Thus when one makes a permanent magnet, it must have both a North and a South pole. This derives from Gauss's law for magnetic fields. 3- What would be the significance of finding a magnetic monopole? No significance. It would just be interesting to find a counter example to the four fundamental equations of electromagnetism. 4- What exactly makes up a magnet? (Particle wise) The source of all magnetism is motion of electrical charges. Every atom of a ferromagnetic material is a tiny magnet, but in scattered directions of its magnetic field. When aligned they form a magnet. 5- What causes magnets to attract some materials more strongly than others? (if at all)? The property of magnetic permeability, and which class of magnetic material said material fits in. Ultimately it boils down to how easy is for the external magnet to create its own alignment of magnetic domains. 6- Why is gravity weaker than all the other forces? It just is.
