What is the electric flux in an object whose normal line is perpendicular to the electric field?

Is electric flux perpendicular to electric field?

Electric flux is proportional to the number of electric field lines going through a virtual surface. … For a non-uniform electric field, the electric flux dΦE through a small surface area dS is given by dΦE=E⋅dS d Φ E = E ⋅ d S (the electric field, E, multiplied by the component of area perpendicular to the field).

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.

For which surface is the electric flux zero?

If there is no net charge within a closed surface, every field line directed into the surface continues through the interior and is directed outward elsewhere on the surface. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.

What is the relationship between electric field and electric flux?

The electric field ( ) is defined as the electric force per unit charge. The electric flux ( )is defined as the electric field times the normal area vector. In Gausses law this quantity is proportional to the amount of charge enclosed by a surface.

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 through a cube of side A If a point charge of Q is at one of its corner?

If the charge ‘q ‘is placed at one of the corners of the cube, it will be divided into 8 such cubes. Therefore, electric flux through the one cube is the eighth part of [dfrac{q}{{{varepsilon _circ }}}].

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.

Why area vector is perpendicular to the surface?

Long story short, if you want to encode information about your surface into a single vector, then a perpendicular area vector is better than any other area vector because it also carries explicit information about the orientation of the surface.
