Magnetism An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field.

What are magnets made from? Magnets are made from a rock called magnetite. For example we will take a bar magnet it is made up of tiny bar magnets, they are called magnetic domains. Magnetic domains only … exist in special kinds of metals such as iron, nickel and cobalt.

- If you've ever played with magnets, then you definitely know that they exert an invisible force on each other. However, there is a very specific direction to these forces depending on which poles are near each other. Another fundamental property of magnets is that similar poles repel, while opposite poles attract.

- Sponsored Links. Magnets are objects that produce an area of magnetic force called a magnetic field. Magnetic fields by themselves are invisible to the human eye. Iron filings can be used to show magnetic fields created by magnets (such as in the picture to the right).

Learn about Magnets Magnets have an invisible field that forces other objects to react to its properties. This powerful force is called the magnetic field. Magnetic fields have particles called electrons that actively shift and move within the field.

Magnet school DeBakey High School for Health Professions in Houston, Texas is a magnet school specializing in medical sciences. In the U.S. education system, magnet schools are public schools with specialized courses or curricula. Magnet refers to how the schools draw students from across the normal boundaries defined by authorities (usually school boards) as school zones that feed into certain schools. There are magnet schools at the elementary, middle, and high school levels. In the United States, where education is decentralized, some magnet schools are established by school districts and draw only from the district, while others are set up by state governments and may draw from multiple districts.

MAGNETISM Use a compass; north points to the south part of the magnet. Magnets (permanent) A magnet that keeps its magnetism for a long time (store magnet).Repels other magnets with the same polarity. It attracts opposite poles. It only attracts some metals. A magnet always has an even number of poles.

What Is Magnetism? 10 hilariously insightful foreign words. The term magnetism describes the force of repulsion and attraction between different substances, such as iron and other metals. In magnetism, the motion of charged particles is ultimately responsible for the attraction or repulsion between substances. Objects that are attracted to each other illustrate the magnetic principles of ferromagnetism and paramagnetism, while diamagnetism describes the repulsion of magnetic fields.

Are all metals attracted to a magnet? Magnets attract to ferrous metals such as iron, nickel, cobalt, certain steels and other alloys. Brass, aluminum, copper, and most stainless steels, however, are non ferrous.

Force between magnets Force between magnets. Magnets exert forces and torques on each other due to the complex rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material.

What is a Magnet? A magnet is an object or a device that gives off an external magnetic field. Basically, it applies a force over a distance on other magnets, electrical currents, beams of charge, circuits, or magnetic materials. Magnetism can even be caused by electrical currents. While you might think of metal magnets such as the ones you use in class, there are many different types of magnetic materials. Iron (Fe) is an easy material to use. Other elements such as neodymium (Nd) and samarium (Sm) are also used in magnets.

All About Magnets Science All magnets have the ability to attract other magnets or magnetic objects (such as iron and some other metal objects). But a magnet doesn't necessarily have to touch a magnetic object for the object to be attracted to it. Try this experiment to learn why.

INTRODUCTION Magnets are pieces of metal that have the ability to attract other metals. Every magnet has two poles: a north and a south. Much like electrical charges, two similar magnetic poles repel each other; while opposite magnetic poles attract each other. Magnets have a continuous force around them that is known as a magnetic field. This field enables them to attract other metals. Figure 1 illustrates this force using bar and horseshoe magnets. The shape of the magnet dictates the path the lines of force will take.

- Magnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a MAGNETIC FIELD. When two magnets come near each other, their fields create forces that attract or repel.

- You may reply that magnets are magnets, they all produce magnetic fields, and whether used by hospitals or alternative therapists, their curative potential is the same. However this fallacy rests on the belief that all magnets are the same. They're not.
