## What is magnetic flux?

## What is magnetic flux Class 12?

Magnetic flux: **The total number of magnetic field lines passing through a given area normal to it** is called magnetic flux. Mathematically it is represented by ϕ and defined as the dot product of magnetic field vector and area vector i.e. given by. ϕ=→B. →A.

## What causes magnetic flux?

**Any induced current in a coil** will result in a magnetic flux that is opposite to the original changing flux. toward a conducting loop, the induced current produces a north pole pointing toward the magnet's north pole. This creates a repulsive force opposing the change that caused the current.

## How do you calculate magnetic flux?

**ΦB=B⋅A=BAcosθ Φ B = B ⋅ A = BA cos ** , where B is the magnitude of the magnetic field (having the unit of Tesla, T), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.

## What is magnetic flux symbol?

A sub-discipline of physics in the field of electromagnetism is the magnetic flux through a surface, which refers to the surface integral of the magnetic field's (B) normal component passing through that surface. ... Magnetic flux is denoted by the Greek letter Phi and has the **symbol Φ or ΦB**.

## What is magnetic flux in physics class 10?

Magnetic flux refers to **the total number of magnetic field lines penetrating any surface placed perpendicular to the magnetic field**. It is calculated as the product of the average magnetic field strength and the perpendicular area it penetrates.May 20, 2020

## What is magnetic flux Class 9?

Magnetic flux is defined as **the number of magnetic field lines passing through a given closed surface**. It provides the measurement of the total magnetic field that passes through a given surface area.

## What is magnetic flux write its SI unit?

The total number of magnetic lines of force crossing any surface in the magnetic field is termed as magnetic flux. ∴ Φ = BA cos θ SI unit of magnetic flux is **weber**.

## What is magnetic flux and its SI unit?

In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or Φ_{B}. The SI unit of magnetic flux is **the weber (Wb; in derived units, volt–seconds)**, and the CGS unit is the maxwell.

## Who invented magnetic flux?

**Nikola Tesla** , was experimenting on generators and he discovered the rotating magnetic field in 1883, which is the principle of alternating current.
