So this electric field vector is going west.
How is the direction of an electric field indicated with electric field lines?
The strength of the electric field is greater when the field lines are close to each other and weaker when they are far from each other. The direction of the electric field is indicated by the direction of the arrow. The direction of the electric field is the same as the direction of the arrow.
How do you determine the direction of an electric field from a magnetic field?
To find the direction of propagation of an E&M wave, point the fingers of the right hand in the direction of the electric field, curl them toward the direction of the magnetic field, and your thumb will point in the direction of propagation.
What is the direction of the electric field at a point directly to the left of a positive charge?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field. The electric field points to the right because the force on a negative charge is in the same direction as the field.
How is the direction of an electric field indicated with electric field lines quizlet?
d) Electric field lines are always directed radially away from a positively charged particle. e) An electric field line indicates the direction of the force on an electron placed on the line. An electric field line indicates the direction of the force on an electron placed on the line.
What is the direction of the magnetic field?
moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.
What is the direction of the electric field and the direction of the magnetic field in an electromagnetic wave?
The electric field of an electromagnetic wave points in the positive y direction. At the same time, the magnetic field of this wave points in the positive z direction.
In which direction does the electric field point at a position directly south of a positive charge?
In which direction does the electric field point at a position directly south of a positive charge? The direction of electric field is radially outward for a positive charge and radially inward for a negative charge. Thus for the electric field points toward SOUTH at a position directly south of a positive charge.

What is the direction of the electric field and the direction of the magnetic field in an electromagnetic wave quizlet?
What is the direction of the electric field and the direction of the magnetic field in an electromagnetic wave? They oscillate perpendicular to one another and both perpendicular to the direction of motion.
What is direction of magnetic field lines?
The lines are directed from north pole to the south pole outside the magnet while they are directed from south pole to north pole inside the magnet. A tangent drawn on a magnetic field line gives the direction of the magnetic field at that point.
What did Maxwell show about the direction of electric field lines?
What did Maxwell show about the direction of electric field lines? The originate on positive charges and terminate on negative charges.
Which statement about the direction of a magnetic field at a point is correct?
The direction of the magnetic field is tangent to the field line at any point in space.
What is the inverted triangle in Maxwell equation?
Divergence. , where the upside-down triangle thingy is called the del operator. Notice that two of Maxwell's Equations use divergence, one for the electric field and one for the magnetic field.
How is the direction of a magnetic field at a location indicated?
Terms in this set (31) How is the direction of a magnetic field at a location indicated? A magnetic field is always directed in the direction that the north pole of a small compass needle points at the location.
Which of the following Maxwell equation can be derived from Faraday law of electromagnetic induction?
Maxwell Third Equation Maxwell's 3rd equation is derived from Faraday's laws of Electromagnetic Induction. It states that “Whenever there are n-turns of conducting coil in a closed path placed in a time-varying magnetic field, an alternating electromotive force gets induced in each coil.” Lenz's law gives this.
Which of the following Maxwell equation can be derived from Gauss law of electrostatics?
The Maxwell's equation ∇⋅E(r)=ρ(r)ϵ0 is derived from the Gauss law in electrostatics (which is in turn derived from Coulomb's law).
How is the direction of a magnetic field at a location indicated quizlet?
Terms in this set (31) How is the direction of a magnetic field at a location indicated? A magnetic field is always directed in the direction that the north pole of a small compass needle points at the location.
What is the direction of the magnetic field at a point outside the surface of the loop?
For the point outside the surface of the loop the direction is outwards (going outside of the plane).
What is electromagnetic induction State Faraday’s law of electromagnetic induction?
Faraday's first law of electromagnetic induction states, “Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. Likewise, if the conductor circuit is closed, a current is induced, which is called induced current.”
What is Maxwell Faraday equation?
∮CE⋅dl=−∂∂t∫SB⋅ds. This general form is known by a variety of names; here we refer to it as the Maxwell-Faraday Equation (MFE).
Which of the following are Maxwell’s equation related to static magnetic field in point form?
Gauss's law for the static electric field….Ampere's circuit law.

What is the direction of the magnetic field at the center point P of the square loop of current?
If the current in this wire is into the page, what is the direction of the magnetic field at point P? Using the right-hand rule to determine the direction of the magnetic field around a wire, the magnetic field will point in the clockwise direction.
What is the direction of the magnetic field at a point on the axis of current carrying circular coil?
The direction of magnetic field depends upon the direction of current passing through that circular loop . If the current is flowing clockwise then the direction of magnetic field is inside the loop along the axis and vice versa.

How can you find out the direction of induced current or emf?
The direction of induced emf is determined by right hand rule. As per the the rule, if the thumb is pointed in the direction of motion of the conductor and the first finger is pointed in the direction of the magnetic field (north to south), then the second finger represents the direction of the induced current.
