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 ...
How are magnetic fields and electric fields related? Where do magnetic lines of force enter Earth? How does an electric field produce a magnetic field? How can a magnetic field be produced around a wire? What determines the strength of a magnetic field? What is the relationship between electri...
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 every appliance, there is one in your computer to turn the hard drive, and there is ...
When you write data to a disk, the information is encoded and stored on the disk's surface using magnetic fields or laser technology. The disk spins at a high speed while a read/write head accesses the data by moving back and forth across the disk's surface. When you want to retrieve...

What is an example of solar wind? The solar wind is composed of plasma that is released by the Sun. The plasma is made up of very hot ionized particles of hydrogen and helium gas. How does solar wind affect Earth? Solar wind can interact with Earth's magnetic fields and excite the ele...

Block storage, sometimes called block-level storage, is a technology for storing data in blocks. The blocks are then stored as separate pieces, each with a unique identifier. Developers favor block storage for computing situations that require fast, efficient and reliable data transfer. ...
Matter—the visible kind, that is—interacts with the universe in many ways. It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating...
