Question

What are the two types of flux?

Answer 1

Hint: A set of imaginary lines across which a physical substance travels is known as flux. In physics, there are two forms of important flux named as electric and magnetic flux.

Complete step by step solution:
(i) Electric flux: The Electric Flux is defined as the rate at which the electric field flows over a specific region, and it is proportional to the number of electric field lines that pass through a virtual surface. It is denoted by \[{\Phi _E}\]. When you turn on the mosquito repellent, you'll notice the scent after a while. As a result, the electric flux is represented by lines (electric field lines) of fragrance moving through the area of the room.

The following are some key terms in the concept of electric flux:
Some of the key phrases that are utilised in the notion of electric flux, and which must be understood in order to grasp the concept of electric flux. The following are the terms:
Electric Field: A field or area around a steady or moving charge in the form of a charged particle, or between two voltages, is known as an electric field. Other charged objects or particles in this space are also subjected to some force from this field, the intensity and type of which is determined by the charge a particle bears.

Electric Charge: In an electromagnetic field, it is a physical property of matter that leads it to experience a force. It also allows the particle to have its own electric field. The charge of an electron is -1, while the charge of a proton is +1. Neutrons have a charge of 0 and do not interfere with other electric charges.

Electric displacement field: The phrase electric displacement field, often known as electric induction, is a vector field that appears in Maxwell's equation and is symbolised by the letter 'D' in physics.

(ii) Magnetic flux: Magnetic flux is the total number of magnetic field lines travelling through a particular area normal to it.


The dot product of the magnetic field 'B' and the Area vector 'A' is the magnetic flux.
\[{\Phi _M} = \overrightarrow B \cdot \overrightarrow A \]
Here, \[\overrightarrow B \] is the magnetic field vector and \[\overrightarrow A \] is the area vector.
In terms of magnitude, it is given as
\[{\Phi _M} = B\,A\,\,\cos \theta \]
Here, \[\theta \] is the angle between the magnetic field vector and the area vector.

Hence, the two types of flux are electric and magnetic flux.

Note: The magnetic flux has physical significance since it represents the entire amount of magnetic field that may pass through a certain area. It's a helpful tool for describing the effects of magnetic force on things in a specific location.
