Since the compass needle is a small magnet, the South end will be attracted to the North pole of your magnet. - A bar magnet sets up a magnetic field in the space around it and a second body responds to that field. at the right. If a bar magnet is cut in half, it is not the case that one half has the north pole and the other half has the south pole. Bar Magnets. By the end of the 19th century all the known elements and many compounds had been tested for magnetism, and all were found to have some magnetic property.The most common was the property of diamagnetism, the name given to materials exhibiting a weak repulsion by both poles of a magnet. The opposite end is called the south pole. These are the most commonly available variety of magnet shapes. Q: Find a snack or drink item in the classroom, or at your next meal. identical, but are slightly different. This means that they are stronger on each end where the pole faces are located. Bar magnets are also commonly used for demonstrations in the classroom. 1) As the magnet enters it generates a current in the loop that sets up a magnetic field to oppose the entry of the magnet. Bar Magnets. Last Minute Deal . If, for example, the separation between the two poles is doubled, the magnetic force diminishes to one-fourth its former value.
