Magnetic Circuit Definition A magnetic circuit is made up of magnetic materials having high permeability such as iron, soft steel, etc. It is the closed path followed by magnetic lines of forces is called magnetic circuit. In the magnetic circuit, magnetic flux or magnetic line of forces starts f.....

### Magnetic Potential

Magnetic Potential Definition Magnetic Potential is the property of certain substances or phenomena that gives rise to magnetic fields. Magnetic Potential, also known as Magnetomotive Force, which is analogous to electromotive force or voltage in electricity. The magnetic vector potential, A, (of.....

### Field Line

Field Line Definition Field Line is a line (line of force), which is used to indicate the direction of a field, especially an electric or magnetic field, at various points in space. The tangent of a line of force at each point indicates the orientation of the field at that point. Arrows are usual.....

### About Photon

About Photon Definition A photon (also called light quantum) is the quantum of electromagnetic radiation. The term quantum is the smallest elemental unit of a quantity, or the smallest discrete amount of something. Thus, one quantum of electromagnetic energy is called a photon. The plural of quan.....

### Cavity Magnetron

Cavity Magnetron Definition Cavity Magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities. It is a source of microwave energy used in medical linear accelerators to ac.....

### Mass Spectrometry

Mass Spectrometry Definition Mass Spectrometry (MS) is a technique for the analysis of a substance in which the molecule is subjected to bombardment by high-energy electrons or atoms to cause ionization and fragmentation to give a series of ions in the gas phase that constitutes the fragmention p.....

### Scalar Field

Scalar Field Definition Scalar Field is a function that gives us a single value of some variable for every point in space. A scalar value is a single component that can assume one of a range of values. An example of this is temperature. In contrast, a vector value has more than one component. An .....

### Line of Force

Line of Force Definition Line of Force is an imaginary line in a field of force, whose tangent at any point gives the direction of the field at that point and whose number through unit area perpendicular to the field represents its intensity. In physics, Line of Forc is a path followed by an elec.....

### Speed of Light

Speed of Light Definition Speed of Light is considered a fundamental constant of nature. Its significance is far broader than its role in describing a property of electromagnetic waves. It serves as the single limiting velocity in the universe, being an upper bound to the propagation speed of sig.....

### Vector Calculus

Vector Calculus Definition Vector Calculus (or vector analysis) is closely linked with the needs of physics and mechanics. It is a field of mathematics concerned with multivariate real analysis of vectors in an inner product space of two or more dimensions; some results are those that involve the.....
