(ii) Like magnetic poles repel each other and unlike magnetic poles attract each other. What is a natural magnet answer? Natural magnets are the magnets that can be found in nature. For example - lodestone Magnets have five properties. Their force of attraction is greater at the poles than in the middle. Similar poles repel. Opposite poles attract. The south pole of a bar magnet suspended by a thread moves toward the north pole. Magnets attract objects made of iron, cobalt and nickel. Every magnet has two poles: north and south
The three properties that all magnets have are that they all attract (or stick to) certain metals, they have north and south poles (ends), and two of the same poles will repel (or push away from. Magnet Lesson Plan Model: 5Es. ENGAGE: Before class begins, put a magnetic marble in your pocket. Put a second magnetic marble and a magazine or thin notebook on your desk. Show the students a magnet magic trick! Hold up the magnetic marble (not the one from your pocket), and say that you can move it however you want—even through a book A magnet always has north and south poles. Cutting a magnet in half makes two magnets, each with two poles. Hammering a magnet will cause it to loose its magnetic properties. Heating a magnet is another way to take away it's magnetic properties. This is because the molecules lose their north-south alignment and get arranged in random directions

Some metals are magnetic. When you bring certain metals close to a magnet the metals are attracted to the magnet. It would appear that the metal sticks to the magnet. Metals that do not have magnetic properties and are not attracted are called non-magnetic Statement 1: When a horseshoe magnet is brought close to a pile of iron filings, more filings will be attracted to the U shaped part of the magnet. Statement 2: Horseshoe magnet has only one pole that is its U-shaped part. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1 The fondest memory of a science experiment every kid has, is with magnets.

Properties. Alnico alloys can be magnetised to produce strong magnetic fields and has a high coercivity (resistance to demagnetization), thus making strong permanent magnets. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or. The magnetic lines of force has the following properties: 1) Each line is a closed and continuous curve. 2) They originate from the north pole and terminate at the south pole. 3) They will never intersect each other. 4) They are crowded near the poles where the magnetic field is strong. 5) They affect the magnetic compass needle CLEAN THIS MESS!

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of. However, when the magnet geometry is ideal or the magnet is used with iron / steel elements in a magnetic circuit, then the Alnico 5 magnets may generate a stronger magnetic field. A good example of this is a horseshoe magnet. A horseshoe magnet has a very long magnetic length and benefits from the NORTH and SOUTH poles being close to each other Introduction to General Characteristics of Solid State. We know that matter generally exist in three states namely; solid, liquid and gas. When we change the physical conditions by altering the pressure and temperature of the surroundings, we find the states to change and transform from one form to another A mixture contains three different substances X, Y and Z. They are of the same size, cubical in shape and yellow in colour. X particles are very heavy, insoluble, non-magnetic and contribute 50% of the mixture. Y particles are very light, insoluble, non-magnetic and contribute 40% of the mixture. And Z particles are iron pieces

The end of a free hanging magnet which point towards North is called Matter can be identified through its properties. One clue to helps us identify matter is magnetism. Magnetism is the ability of a material to be attracted by a magnet. Only certain materials are attracted to magnets, like iron, nickel, and cobalt. Another property that can help us identify matter is solubility These two ends are the magnetic poles. The force of a magnet is strongest at the poles. If you tie a string to the middle of a bar magnet, the north end will point north and the south end will point south. The earth is like a giant magnet! The magnetic fields surrounding earth are near the North Pole and the South Pole Chemical Properties of Oxygen. At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O 2. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element Soft magnets, on the other hand, are those that lose their magnetic charge properties over time. Additionally, paramagnetic objects are those that can become magnetic only when in the presence of an external magnetic field. A magnetic field is the space surrounding a magnet in which magnetic force is exerted..
Magnetic properties of matter. All matter exhibits magnetic properties when placed in an external magnetic field.

What types of magnets exist in the world? First, a definition. Magnets are solid objects that attract iron or steel. Magnets do this by a phenomenon called magnetism, in which they generate a force that extends into a (magnetic) field (i.e., the area around the magnet).. A magnet may have the ability to do this naturally, such as lodestone, or it may acquire the ability when combined with. Electric, and magnetic forces between a pair of objects do not require that the objects be in contact. The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. Alignment agreement
Methods of Making Permanent and Temporary Magnets. 1. Making the Virtual Magnets:-. The virtual magnets are the ones that borrow magnetic properties from the permanent magnets. Take some permanent magnet and attach it to some iron nail, the iron nail will now have the magnetic properties and when this iron nail will be touched to the other iron. Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. Learn more about magnetism in this article

The poles of a magnet are the two points near but within the ends of the magnet, at which the entire magnetism can be assumed to be concentrated. The poles always occur in pairs and they are of equal strength. Like poles repel and unlike poles attract. Properties of Magnet (i) A freely suspended magnet always aligns itself into north-south. Then new magnetic moment. M' = M / 2. Original magnet MOS is bent at O, the mid point at 60°.All sidesare equal; The mutual interaction force between two small magnets of moments M 1 and M 2 is given by; F = K 6M 1 M 2 / d 4 in end- on position. Here,d denotes the separation between magnets. Magnetic length = 5 / 6 * geometric length of magnet
