What are magnetic fields made of? A tremendous amount of research has gone into the area of elementary particle physics - the study of the basic building blocks of all the matter we know of. We used to think that electrons, protons, neutrons and photons were all there was. However, we ...
What are magnetic fields made of? What are magnetic poles? What is magnetic intensity? What is a magnetic field, how is it defined and what does it tell you? What is magnetism? Define Magnetic Field. What are magnetic waves? What is a magnetic dipole?
What material is an umbrella made? How much work was done in stopping the bullet? What would happen if you shoot a bullet in the sand at the beach? What is a photonic bandgap material? What are magnetic fields made of? What is Ballistic Galvanometer?
In the 1950s a new group of magnets was developed. Hard hexagonal ferrites, also called ceramic magnets, can be cut into thinner slices and be exposed to low level demagnetizing fields without losing their magnetic properties. They also are cheap to make. The molecular hexagonal ferrite structure...
Both the magnet frame and the metal plate are made of aluminum. Aluminum magnetic catches are lightweight, durable and highly resistant to corrosion. They also offer a sleek chrome finish that’s aesthetically pleasing. Brass Brass is commonly used in the construction of magnetic catches. Brass,...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. ...
Motors use magnetic fields to rotate a shaft. As the electric current going to the motor varies–all generated currents do, it causes the rising and falling magnetic fields to push the core of the motor around. Motors are ubiquitous–at least a dozen are in your car, there is one in eve...

structure. All objects in the universe are made of atoms, and each atom has a nucleus at its center. Tiny particles called electrons orbit the nucleus, creating magnetic fields around them. Magnetism occurs when the electrons spin in the same direction. As all the magnetic forces from the ele...
Magnets are materials that produce magnetic fields, which attract specific metals. Every magnet has a north and a south pole. Opposite poles attract, while like poles repel. While most magnets are made from metals and metal alloys, scientists have devised ways to create magnets from composite mat...
