What do you mean by electric flux in electrostatics?
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force. Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.
Why 2 magnetic fields cannot cross each other?
the tangent at any point on an electric field line gives the direction of the field at that point . so if field lines intersect then electric field at will have more than1 direction which is impossible
How are magnet fields and electric fields alike?
Both act only on charged particles (ions, protons, or electrons). ?However, an electric field (which generates an ELECTRIC FORCE) acts on a particle in the same direction as the field, given by the equation:F(vector) = q*E(vector)The resulting force vector is in the same direction as the field vector (for positive charges).A magnetic field generates a force ONLY on a MOVING charge, and ONLY if the charge is moving non-parallel to the magnetic field:F(vector) = q*v(vector) x B(vector)Because of the cross-product, the magnetic force is a direction perpendicular to the velocity and magnetic field vectors (use the right hand rule to figure out the direction of magnetic force). ?The particle will still have momentum from its initial velocity, so an applied magnetic field will (pretty much) always make the particle move in a curved path.
The solar wind blows in a direction?
The solar wind blows outward in all directions from the Sun, carrying with it charged particles such as electrons and protons. The direction of the solar wind is influenced by the Sun's rotation and the varying magnetic fields on its surface.
What is the relationship between the direction of an electric field and the direction of the force that the field would exert?
The direction of an electric field is the direction of the force that the field would exert on a proton.. ___ The relationship of the direction of an electric field and the direction of force that the field would exert are the same. Let's look. Consider the humble electron, the carrier of the negative electrostatic force. The electric field around the electron can be said to "stand out around the electron" equally and in all directions. We need to form a mental picture, so let's try to do that. Think of the electron as a little ball floating in space. Now picture it with long, thin "needles" sticking out of it in all directions. Each needle is a line of electric force, and its direction is "out" or "away" from the center of the ball that is the electron. Got that picture? The negative electric force about any elementary charged particle is just like the picture we have of the electron and its electric field. The force acts "out" like that. In the case of a positively charged particle, the same model applies, except that positive and negative forces attract while two negative or two positive forces repel each other, just as is set down in the law of electrostatics. Simple and easy. Note that electric and magnetic fields have a little different way of interacting, and this question doesn't cover that.
How is the induced surface charge affected by external electric fields?
The induced surface charge is influenced by external electric fields. When an external electric field is applied, it can attract or repel charges on the surface, causing the distribution of charges to change. This can result in an increase or decrease in the induced surface charge depending on the direction and strength of the external electric field.
What fields gravational magnetic or electric can only exist in one direction?
Gravitational fields are always attractive, meaning they only exist in the direction of pulling objects closer together. Magnetic fields can exist in any direction in space, while electric fields can exist in a specified direction due to the sign of the charge producing it.
What best describes an equipotential surface and its significance in the context of electric fields?
An equipotential surface is a surface where all points have the same electric potential. In the context of electric fields, it signifies that no work is required to move a charge along that surface, as the electric field is perpendicular to the surface. This helps in visualizing the electric field lines and understanding the distribution of electric potential in a given region.
What is the significance of an equipotential surface in the context of electric fields?
An equipotential surface in the context of electric fields is significant because it represents points that have the same electric potential. This means that no work is required to move a charge along an equipotential surface, making it a useful tool for understanding the behavior of electric fields and the distribution of charges in a given space.
What is the right hand rule for determining the direction of the electromagnetic wave's electric and magnetic fields?
The right hand rule is a method used to determine the direction of the electric and magnetic fields in an electromagnetic wave. Point your right thumb in the direction of the wave's propagation (movement), your fingers will curl in the direction of the electric field, and your palm will face in the direction of the magnetic field.
Do electric or magnetic fields point away from positive charges?
Electric fields point away from positive charges, while magnetic fields do not have a specific direction with respect to positive charges.
In an electromagnetic wave, in what direction do the electric and magnetic fields point towards each other?
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other.
What is the difference between positive and negative electric fields?
Positive electric fields point away from positive charges and towards negative charges, while negative electric fields point towards positive charges and away from negative charges. In both cases, the direction indicates the direction that a positive test charge would move if placed in that field.
What is the direction of propagation of an electromagnetic wave?
An electromagnetic wave propagates in a direction perpendicular to both the electric and magnetic fields.
What is the application of the electromagnetic wave right-hand rule in determining the direction of the electric and magnetic fields in a propagating electromagnetic wave?
The electromagnetic wave right-hand rule is used to determine the direction of the electric and magnetic fields in a propagating electromagnetic wave. By using your right hand with your thumb pointing in the direction of the wave's propagation, your fingers curl in the direction of the electric field, and your palm faces in the direction of the magnetic field. This rule helps visualize the relationship between the fields in the wave.
How is the direction of an electric field indicate with electrical fields lines?
The direction of an electric field is indicated by the direction in which the electric field lines point. Electric field lines point away from positive charges and towards negative charges. The closer the field lines are together, the stronger the electric field in that region.
What do you mean by electric flux in electrostatics?
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force.
