As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.

What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
What is meant by electric and magnetic field?
A magnetic field is a area in which magnetic objects are pushed or pulled. It is caused by the alignment of parts of atoms.A field of force associated with changing electric fields , as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges. Most magnets have magnetic fields as a result of the spinning motion of the electrons orbiting the atoms of which they are composed; electromagnets create such fields from electric current moving through coils. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. See Note at magnetism.
How does a tangent at any point on the magnetic field line show the direction of magnetic field at that point?
This is true for any contiguous function, not just magnetic fields.
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
Does any force act on a point charge is moving in a electric field at right angle to the field line?
Yes. A force acts on the charge perpendicular to the plane defined by the charge velocity and the electric field line of force. The Electric field is is equivalent to and magnetic field E=cB, where c is the speed of light. This causes a power field P= cqvxB = c(qvxB) = cForce. Maxwell was the first to predict that light was a form of electricity when he found this relationship, E=cB. Maxwell noticed that light and electric fields had the same speed, c.
What is magnetic field?
A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles.Read more: magnetic-field
Which is true of magnetic field lines but not electric field lines?
they show wich way iron shavings would align themselves They always make closed loops. Electric field lines can either form closed loops or they can start and finish on isolated electric charges. Magnetic field lines always only form closed loops.
What kind of field is electricity?
Electrostatic field surrounds a stationary charge. A moving charge has magnetic and electric field surrounding it. But since the mag. field at a point due to the moving charge keeps changing, there is also an induced electric field. this ind. electric field in turn induces a magnetic field. and this goes on in a cycle. (Maxwell equation)
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
Difference between electric field and magnetic field?
the basic difference is the origin point. the magnetic field originates due to magnetic dipole and the electric field originates due to the charged particles. An electric field surrounds electrically charged particles and time-varying magnetic fields. It can be said Electric fields are generated around particles that bear electric charge or where magnetic field is changing with time Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. It can be said a moving charge produces magnetic field. In magnetic material moving electrons contribute magnetic field(In non-magnetic material, paired electrons spin in opposite directions, their magnetic fields cancel one another out)

What is the left hand rule for conductors?
The left hand rule for conductors says that your fingers will point in the direction of the resulting magnetic field. The magnetic field is produced by the electron flow.
What is a neutral point?
The point in the magnetic field at which the horizontal components of earth's magnetic field and the magnetic field due to magnet are exactly opposite & equal is known as neutral point.
What is the neutral point of the magnet?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
An electric current produces?
Produces magnetic fields, that are used in generators, inductors and motors. The magnetic field at any given point is specified by both a magnitude and a direction.
How does a tangent at any point on the magnetic field line show the direction of magnetic field at that point?
This is true for any contiguous function, not just magnetic fields.
A charge q is moving with a velocity v in free space write an expression for magnetic field produce at any point by this charge?
The magnetic field produced by this charge is B=( qz/r^2)v/c.
