What are the conditions for maximum and minimum flux?
if the enclosed charge in the gausian surface is maximum then the flux through the surface is also maximum. & if the enclosed charge is minimum then the flux is also minimum. since flux is directly proportional to the enclosed charge.
When the magnetic flux is maximum and minimum?
The magnetic flux through an area element is (i) maximum when the magnetic induction is the direction of the area vector, and (ii) Zero when the magnetic induction is perpendicular to the area vector.
What is maximum flux?
MAXIMUM FLUX If the surface is placed perpendicular to the electric field then maximum electric lines of force will pass through the surface. Consequently maximum electric flux will pass through the surface.
How do you find the maximum flux?
The formula for Maximum flux = V1= 4.44F∅N1 or V2=4.44F∅N2.
At what angle is electric flux minimum?
The electric flux through the surface is minimum when the angle between e and a is. salonitomar2770 is waiting for your help.
Which case has maximum flux?
Therefore, the electric flux of a surface is maximum when the area vector is parallel to the direction of the electric field.
When can you get maximum electric flux?
The electric flux of a surface is maximum when the area vector is parallel to the direction of the electric field. The electric flux is the total number of lines of force passing through a surface.
Why is induced EMF maximum when magnetic flux is minimum?
Induced EMF is maximised when the CHANGE in magnetic flux is maximised. This simultaneously occurs when the flux THROUGH the coil is minimised. In a hypothetical motor, magnetic flux through the coil is maximised when the coil cuts the magnetic field, as we know.
When is the flux linking the coil is zero?
I should have mentioned that for this example the flux is zero when the derivative is max so there is a relationship between the flux and the rate of change of flux, but most important is that the rate of change is not zero and that’s how we get the EMF.
When is the emf of a coil is high?
EMF depends on the rate of change of flux, not the flux itself. Thus when the rate of change of flux is high, the EMF is high. It doesnt matter that the absolute value of the flux itself is zero or not, as long as it is changing quickly.
How does Faraday’s Law of induction work in a coil?
area (1) Faraday’s Law states that a change in magnetic flux can induce a voltage in a coil of wire. This is known as the induced emf. V = -N dΦ dt (2) where dΦ/dt is the rate of change of the flux Φ and N is the number of turns in the coil.
