Tiếng ViệtNowadays, in the field of electrical engineering and physics, magnetic flux is no longer a strange concept for the learners. However, there are still many people who do not know what flux is despite being exposed to a lot of flux. So what is flux? the unit of flux is? and maximum flux, please also TTTT Global learn about.

What is flux ?
What is flux TTTT ? In today’s engineering field, flux is a quantity that represents the flux of magnetic field lines passing through an electric charge. The magnetic flux is directly related to the flux density. The magnetic flux is also known as the integral of the dot product between the flux density and the component vector of the charge over the total charge.
In addition, magnetic flux is also known as a magnetic field generated from within a coil of copper wire. Depending on the number of turns the winding is made to meet the needs of the winding application. This number of turns of wire will pass through a bar of permanent magnets.
What is the maximum flux and the unit of flux ?
Maximum flux
The maximum flux is generated when the angle is in the two cases of vector n and vector B producing angles of 0 degrees and 180 degrees. It also means that the electromagnetic induction and the magnetic field of cross section S run parallel to each other and do not produce any angle.
The minimum magnetic flux is the case of no flux generation with an angle of 90 degrees that occurs when vector n and vector B form a right angle.
What is the unit of flux ?
The unit of magnetic flux is Weber per square meter or the most commonly used is the Tesla.
The flux is calculated using the following parameters:
- The total number of turns of wire that make up the wireframe.
- Present for magnetic induction lines.
- Electric charge.
- The angle is created from 2 normal vectors of wireframe and magnetic induction (vector n and vector B).
The magnetic flux will always be positive when the required angle values a must be an acute angle.

Particular flux and its applications
Specific magnetic flux is a quantity that occurs when a current with amperage I flows through a closed circuit. The current I induces a magnetic field, which induces a magnetic flux through the closed circuit.
Applications of flux are very diverse and rich such as:
- Generation of Alternating Current: An important application of an electromagnetically induced flux phenomenon is the generation of alternating current. This process is also known as converting mechanical energy into electrical energy .This application is used in Mecc Alte alternator.
- Alternating Alternating Current: This is the same very important application of the common word used in transformers. A transformer is a device that changes alternating current from one voltage level to another through a flux.
- Induction hob: Induction hob works on the principle of mutual induction, when current flows through a copper coil placed inside the cooktop, it creates a changing magnetic field. This alternating or changing magnetic field induces an electric current to flow and we know that current always generates heat.
- Types of Flow Sensors: Electromagnetic flow meters or flow sensors are used to measure the velocity of some fluids which are also based on magnetic flux. When a magnetic field is applied to an insulating tube in which liquid is flowing, an electromotive force is generated and calculated giving the velocity of the fluid.
