To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
How do electromagnetic waves carry energy? How is the magnetic field of an electromagnet controlled? How do transformers work in Ampere's law? How do transistors work? Can an atom become charged? If so, how? What happens when you put a charged particle next to a conductor?
Is infrared light made of mechanical waves? What are the different types of infrared waves? How do electromagnetic waves work? How are mechanical waves produced? How do infrared lasers work? How are standing waves produced? How are electromagnetic waves produced in an antenna?
Thanks to our old friend wave-particle duality, electrons (which we normally think of as particles) can behave like waves (just as waves of light can behave like particles). The faster they travel, the smaller the waves they form and the more detailed the images they show up. Having ...

Microwave ovens cook foods by injecting them with, surprise, microwaves—a form of energy. These electromagnetic waves are invisible to the human eye and fall between radio waves, which are longer in wavelength, and infrared waves, which are shorter. Inside the guts of a microwave, a device ...
It states that when x-rays or other electromagnetic waves are scattered off of a crystal, the angle at which they are scattered is dependent on the spacing between the crystal planes. This allows scientists to determine the atomic structure of a crystal by analyzing the diffraction pattern of ...
How do polarized sunglasses work electromagnetic waves? Light—just like all electromagnetic waves—propagates through the electromagnetic fields. ... Polarization through reflection happenswhen light hits a non-metallic surface. As light hits the surface plane, the vibrations increase in the same plane...
Thomas Seebeck (1770-1831): Discovered the “Seebeck Effect“. Michael Faraday (1791-1867): Electromagnetic induction. He also explained howelectric currentworks. James Maxwell (1831-1879): Translated Faraday’s theories into mathematical expressions. ...
How do Rossby waves form? How do particles move in transverse waves? How does electromagnetic radiation travel? How are longitudinal waves produced? How do P waves move? How do pressure waves propagate across space? How are electromagnetic waves measured? How do electromagnetic waves transfer energy...
