The potential difference. The electrons flows from a lower potential to a higher potential. The electric current flows in the opposite direction. The electric field's direction is always from a higher potential to a lower potential. Its kind of like a waterfall. The water always falls down not up. It goes from a higher potential to a lower potential.
Fleming Right Hand Rule
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
Protons are positively charged that's why they show electric field while magnetic field develops when electric field is in either direction so protons develops magnetic fields also.
A plane including the direction of light propagation and the direction of electric field is called the "plane of vibration". The "plane of polarization" is a confinement of the electric/magnetic field vector to a given plane along the direction of propagation.
The right hand grip rule. You point the thumb on your right hand in the direction of the electric current and curl your fingers. The direction of your fingers gives the direction of the lines of flux. It is undetermined what actually causes the induced charge to always be in this direction but it is probably a function of the electrons spin.
Direction of the electric field vector is the direction of the force experienced by a charged particle in an external electric field.
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
yes,the direction of electric force on a charge is tangent of field lines.
It has plenty of direction. The direction of the electric field at any point in it is the direction of the force that would be felt by an infinitesimally small positive charge placed at that point.
The potential difference. The electrons flows from a lower potential to a higher potential. The electric current flows in the opposite direction. The electric field's direction is always from a higher potential to a lower potential. Its kind of like a waterfall. The water always falls down not up. It goes from a higher potential to a lower potential.
Electric field intensity is related to electric potential by the equation E = -dV/dx, where E is the electric field intensity, V is the electric potential, and x is the distance in the direction of the field. Essentially, the electric field points in the direction of decreasing potential, and the magnitude of the field is related to the rate at which the potential changes.
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation
Introduce two opposite charged objects one AT A TIME and if they move IN THE SAME DIRECTION, they are in a gravitational field, if they move IN DIFFERENT direction they are in an electric field.

The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
No, they only help us understand electric fields.
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
