define magnetic flux and electromagnetism
Answers
Answer:
The magnetic flux is nothing but magnetic field!
Explanation:
whenever the magnetic flux linked with coil changes an induced EMF is produced in it. This is called electromagnetsm
Answer:
In electromagnetism, a sub-discipline of physics, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field (B) passing through that surface. Denoted by Φ or ΦB. The CGS unit is the Maxwell and SI unit of magnetic flux is the Weber (Wb).
What is Magnetic Flux?
Magnetic Flux is defined as the number of magnetic field lines passing through a given closed surface. It gives the measurement of the total magnetic field that passes through a given surface area. Here, the area under consideration can be of any size and under any orientation with respect to the direction of the magnetic field.
Magnetic Flux Symbol
Magnetic flux is commonly denoted using greek letter Phi or Phi suffix B.
Magnetic flux symbol: Φ or ΦB.
Magnetic Flux Formula
Magnetic flux formula is given by:
ϕB=B.A=BAcosΘ
Where,
ΦB 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
Magnetic Flux Unit
Magnetic flux is usually measured with a fluxmeter. The SI and CGS unit of magnetic flux is given below:
SI unit of magnetic flux is Weber(Wb).
The fundamental unit is Volt-seconds.
The CGS unit is Maxwell.
