When the surface is held perpendicular to the field lines the flux will be?

If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the vector, →A, then the flux through that surface is maximal. If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero.

At what angle is flux zero and maximum?

Now if E is perpendicular to the surface then two vector will be parallel so angle between them will be zero and cos 0 =1 so the flux will be maximum.

What is the flux through the plane taken perpendicular to the field?

Answer: The magnetic flux through a unit area perpendicular to the field is Magnetic Flux Density. – It is defined as the amount of magnetic flux passing through per unit area of a section which is perpendicular to the direction of field.

When the electric field vector is perpendicular to the surface?

A vector dot product gives you the projection of a vector along another vector. The area vector is defined as the area in magnitude whose direction is normal to the surface. The above equation gives the amount of →a that is along the direction of →b times the vector b.

Why must the electric field at the surface of a conductor be perpendicular to the surface?

The mutual repulsion of excess positive charges on a spherical conductor distributes them uniformly on its surface. The resulting electric field is perpendicular to the surface and zero inside.

When the magnetic flux is minimum and maximum?

Magnetic flux is maximum when the angle between the magnetic field and the normal to the plane of finite area is 0∘.

What is the use of introducing the ideas of magnetic flux and magnetic flux density?

What is the use of introducing the ideas of magnetic flux and magnetic flux density? Magnetic flux and flux density help in understanding the concept of electromagnetic induction and relation between electricity and magnetism.

When the magnetic field is parallel to the plane?

When the rectangular coil is parallel to the direction of the magnetic field, the induced current is zero. It is because, effectively, zero or no magnetic field lines are linked to the cross-section of the coil.

What is the flux of a vector field through a given area?

The field lines of a vector field F through surfaces with unit normal n, the angle from n to F is θ. Flux is a measure of how much of the field passes through a given surface. F is decomposed into components perpendicular (⊥) and parallel ( ‖ ) to n.

Why electric field lines are always perpendicular to the surface?

An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface.

Is electric flux zero when an electric field is perpendicular?

Yes, electric flux is zero when an electric field is perpendicular but not at a surface. It is zero when it is perpendicular to the area vector as E.S=EScos (90)=0. I think electric flux is at maximum when the field is perpendicular or normal to the plate surface.. And minmum when in parallel as in zero..

When is the electric flux at its maximum?

It is zero when it is perpendicular to the area vector as E.S=EScos (90)=0. I think electric flux is at maximum when the field is perpendicular or normal to the plate surface.. And minmum when in parallel as in zero.. Zero as in no flow condition will occur or transpire..

What does it mean if the electric field is perpendicular?

I think you meant to say “parallel.” Electric flux through a surface is at *maximum* when the electric field is perpendicular to the surface. The whole point of flux is to measure the “total number of field lines” punching through a surface. If the electric field is lying *along* the surface, it isn’t going in or going out and the flux is zero.

Why is flux taken as number of lines passing through an area?

This is because flux is taken as number of field line passing to an area and field line can pass only a perpendicular area or parallel to area vector.
