When the magnetic flux through a closed surface is zero, it means that the magnetic field lines entering the surface equal the field lines leaving it. This can occur when the surface encloses no magnetic sources or when it lies parallel to the magnetic field lines. Mathematically, it can be expressed as ∮B⋅dA = 0, where B is the magnetic field and dA is the differential area vector.

What does magnetic flux mean in physics?
Magnetic flux is a measure of the magnetic field through a given area. It quantifies the number of magnetic field lines passing through a surface. It is an important concept in electromagnetic theory and plays a crucial role in understanding magnetic phenomena.
What will be value of flux if the surface does not enclose any charge?
If the surface does not enclose any charge, the electric flux through the surface will be zero. This is because electric flux is a measure of the total electric field passing through a surface, and if there are no charges within the surface, there will be no electric field passing through it.
Does constant magnetic flux in a coil induce a current in it?
Faraday's Law: the E.M.F. induced in a conductor [the current is caused by the E.M.F.] is directly propotional to the rate of change of magnetic flux linkage.A constant magnetic flux isn't changing, so the rate of change is zero and the induced E.M.F is zero. No E.M.F. = no current.
What is no flux condition?
Flux means the rate of change of magnetic field lines through a particular region in space. Magnetic field lines are imaginary lines drawn to demonstrate the magnetic field through a region in space. No flux condition means the magnetic field lines in the observed region in space is uniform throughout the experiment.
Where the vertical component of earth's magnetic field is zero?
The vertical component of Earth's magnetic field is zero at the magnetic equator, where the magnetic field lines are horizontal. At the magnetic equator, the magnetic field lines run parallel to the Earth's surface, resulting in a zero vertical component.

Can there be any magnetic flux through closed surface?
No, according to Gauss's law for magnetism, the total magnetic flux through a closed surface is zero. This is because magnetic monopoles do not exist, so the magnetic field lines always form closed loops.
What will be value of flux if the surface does not enclose any charge?
If the surface does not enclose any charge, the electric flux through the surface will be zero. This is because electric flux is a measure of the total electric field passing through a surface, and if there are no charges within the surface, there will be no electric field passing through it.
What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
A loop of wire is placed in a uniform magnetic field.In which orientation of the loop is the magnetic flux linked with it maximum?
1. The orientation giving the maximum magnetic flux would be 90 degrees or perpendicular to the magnetic field because that gives the maximum amount of magnetic field lines able to pass through the area of the coil. The greater density of field lines gives a greater magnetic field. The orientation that would give a magnetic flux of zero is the plane of the coil to be parallel to the magnetic field, making no lines pass through the coil and thus no flux.
Does constant magnetic flux in a coil induce a current in it?

A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
What happens if the relative speed between the rotating flux of stator and rotor of the induction motor is zero?
if the relative speed of magnetic flux of stator and rotor becomes zero there will be no back emf and eventually the rotor gets zero speed
What is flux residue?
When large magnetomotive force is applied to the core and then removed. The flux in the core doesn't reach zero. Instead, a magnetic field is left behind in the core. This magnetic field is called residual flux in the core. MOHSIN BB-EE-NED
What is flux inegral?
A flux integral is the summation of the component of a vector field perpendicular to differential surface areas (or in the direction of their normal vectors) over the entire surface. In other words, the flux of a vector field across a surface is the surface integral vector field in the direction of the normal component of the surface.INT INTS[(F*n)dS]INT INT is the double integral operatorS is the surface domain being integrated overF is a vector field* is the dot productn is the normal component to the surfacedS is the differential surface area.Flux integrals are very useful in physics. Two of Maxwell's equations involve flux integrals:INT INTS[(B*n)dS] = 0This equation states that the magnetic flux over a closed surface is always equal to zero. This equation reflects the fact that magnetic monopoles do not exist.INT INTS[(E*n)dS] = Q/EThis equation states that the electric flux through a closed surface is proportional to the total charge enclosed within that surface (1/E is the proportionality constant). These equations played important roles in the discovery of electromagnetic radiation.also the Flux of a velocity field through a surface indicates the flow rate across that surface.
What is difference between an AC and DC flux?
As happens with voltage and current, flux is steady for dc but keeps altering for ac. A transformer works through the ac flux in the magnetic core.
What is no flux condition?
Flux means the rate of change of magnetic field lines through a particular region in space. Magnetic field lines are imaginary lines drawn to demonstrate the magnetic field through a region in space. No flux condition means the magnetic field lines in the observed region in space is uniform throughout the experiment.
