"Magnetic fields are vector fields associated with magnetic forces. Magnetic fields are generated by Hard Ferromagnets. Unlike electric fields, magnetic fields always make closed loops and are never c ...

"Magnetic domains are collections of magnetic fields in the same direction. They are often found in ferromagnetic materials because their atoms align with magnetic fields in a process called a ferroma ...

"Lorentz force is the force on charge in electromagnetic field. Lorentz force is determined by the formula F = qv x B, in which q is the charge, v is the velocity, and B is the magnetic field density. ...

"Longitudinal waves are waves which move particles in the direction of the wave motion. They are the counterparts to transverse waves which move particles parallel to the direction of wave motion. " ...

"Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it. We calculate liquid ...

"Linear motion is the motion that is natural to an object: moving in a straight line. According to Newton’s First Law of Motion, an object not affected by any force will continue indefinitely in a str ...
"Amplitude measures how far a wave rises and falls. A wave's amplitude is defined as half the distance from its highest point to its lowest point. Amplitude is proportional to the energy of a wave, a ...

"Ampere's Law was discovered in 1819 by Ampere. Ampere's Law states that currents generate magnetic fields or in other words, whenever you have a current, there is a magnetic field circulate around it ...

"Light quanta, called photons, are the smallest discrete amounts of light. For light quanta, we use the formula the energy of a photon = planck's constant x frequency. Because this is the smallest dis ...

"The lens equation allows us to understand geometric optic in a quantitative way where 1/d0 + 1/di = 1/f. The lens equation essentially states that the magnification of the object = - distance of th ...
