Magnetic Flux: It is a measure of the amount of magnetic field passing through a given area. It is defined as the product of the magnetic field strength and the area perpendicular to the direction of the magnetic field. It is an important concept in electromagnetism, and it plays a crucial role in understanding many phenomena, such as electromagnetic induction, Faraday’s law, and Lenz’s law.

Symbol & Units of Magnetic Flux

• It is commonly denoted using the Greek letter Phi or Phi suffix B.
• It symbol: Φ or Φ_B.
• It is usually measured with a flux meter.
• The SI unit is Weber (Wb).
• The fundamental unit is Volt-seconds.
• The CGS unit is Maxwell.

Formula of Magnetic Flux

Mathematically, it can be expressed as:

Φ = BAcos(θ)

Where,

• Φ_B is the magnetic flux.
• B is the magnetic field
• A is the area
• θ the angle at which the field lines pass through the given surface area.
