What is the difference between flux and divergence? Flux refers to the flow of a vector quantity through a surface, while divergence is a scalar value that represents the rate of expansion or contraction of a vector field at a given point.
What is the divergence of flux? The divergence of flux refers to the behavior of a vector field as it spreads out or converges at a certain point. It’s a measure of the “source” or “sink” behavior of the field.
How much flux would pass through the surface? The amount of flux passing through a surface depends on factors like the strength and orientation of the vector field, the angle between the field and the surface normal, and the surface area.
What is the law of magnetic flux? The law of magnetic flux states that a changing magnetic flux through a closed loop induces an electromotive force (EMF) or voltage in the loop.
What is the flux from charge outside the cube? The flux from a charge outside a cube is calculated by considering the electric field lines that pass through the cube’s surfaces due to the external charge.
Is flux through a sphere the same as a cube? The flux through a sphere and a cube will differ based on factors like the charge distribution, distance from the charge, and the orientation of the surface relative to the field.
What is outward flux? Outward flux is the amount of a vector field that passes through a closed surface in the outward direction, indicating the flow of a quantity away from the enclosed region.
How to calculate flux? Flux can be calculated by taking the dot product of the vector field and the surface normal vector, and then integrating this dot product over the surface.
Is outward flux always positive? Outward flux is considered positive when the vector field passes through the surface in the outward direction, but it can be negative if the field enters the surface.
What does a negative flux mean? A negative flux indicates that the vector field is entering the surface rather than exiting it. It represents a flow inward.
What does negative flux indicate? Negative flux indicates that the vector field is entering the surface, which is often associated with a “sink” behavior or inward flow.
What does it mean if the electric flux through a closed surface is negative? If the electric flux through a closed surface is negative, it means that more electric field lines are entering the surface than exiting it. This could be due to a net negative charge enclosed.
Why the electric flux entering a closed surface is negative? The electric flux entering a closed surface is negative when more electric field lines are entering the surface than exiting it, which typically happens when there is a net negative charge enclosed.
Why two magnetic flux coming out from a closed surface is always equal to zero? According to Gauss’ law for magnetism, magnetic monopoles do not exist. As a result, the total magnetic flux entering and exiting a closed surface is always zero.
What does the net flux through a closed surface depend on? The net flux through a closed surface depends on the amount of the vector quantity passing through the surface, taking into account both incoming and outgoing contributions.
What is the right hand rule for flux direction? The right-hand rule for flux direction helps determine the direction of the magnetic flux relative to the orientation of the surface and the magnetic field. It’s often used in situations involving electromagnetic induction.
Which rule is used to find direction of flux? The right-hand rule is commonly used to find the direction of flux, especially in cases involving magnetic fields and electromagnetic phenomena.
What direction does flux go? The direction of flux depends on the orientation of the surface and the vector field. It can be inward, outward, or parallel to the surface, depending on the scenario.
