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.
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.
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.

A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
What fields gravational magnetic or electric can only exist in one direction?
gravitational
Are electric field lines real?
No, they only help us understand electric fields.
Can an electric field be compressed?
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
What is the difference between Transverse Electrical mode and Transverse Electrical Magnetic mode?
Transverse modes are classified into different types:TE modes (Transverse Electric) no electric field in the direction of propagation.TM modes (Transverse Magnetic) no magnetic field in the direction of propagation.TEM modes (Transverse Electromagnetic) no electric nor magnetic field in the direction of propagation.Hybrid modes nonzero electric and magnetic fields in the direction of propagation.
What are the factors affecting the mivement of electrons in an electric field in which direction do the electrons deviate in an electric filed and why?
There are a few factors that affects the movement of electrons. The main factor would be crossed fields.
How are moving electric charges related to electric and magnetic fields?
Moving electric charges create electromagnetic fields.
When a conductor is charged the charge moves to the outer surface of the conductor?
True. For instance in a wire, all of the charge is carried on the outside surface of the wire, and not down the center. Why?? Because when the electricity flows down the wire it causes alternating magnetic fields which cause alternating eddy currents within the wire. An eddy current is bascially an electromagnetic area of turbulence, and in this instance makes the flow of electrons easier on the outer edge of the wire. The higher the frequency that the electricity flows through the wire, the stronger the eddy currents and a thinner section of wire will carry the charge.
What is the difference between positive and negative electric fields?
Positive electric fields attract negative charges while negative electric fields attract positive charges.

What do electric fields start with?
Electric fields start on positive charges and terminate on negative charges..
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields
Electric field lines show the strength and what of an electric field?
Direction and electric flux density. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines.
