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.
What is the neutral point of the magnetic field?
The neutral point of a magnetic field is the point in space where the magnetic field intensity is zero. At this point, the magnetic forces acting on a particle will cancel each other out, resulting in no net force. This occurs in regions where magnetic field lines from opposite directions meet and cancel each other.
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 does a tangent at any point on the magnetic field line show the direction of magnetic field at that point?
The tangent to a magnetic field line at any point indicates the direction of the magnetic field at that specific location. This is because the tangent line represents the direction a compass needle would point if placed at that point on the field line. The magnetic field lines themselves flow from the north pole of a magnet to its south pole, with the tangent pointing in the direction the magnetic field would act on a north pole.
How does earth's magnetic field affect the compass?
Earth's magnetic field is what allows a compass to align itself with the magnetic poles, causing the needle to point north. The magnetic field provides a reference point for navigation, helping people determine their direction relative to the Earth's magnetic field. Any changes or disturbances in the magnetic field can affect the accuracy of a compass reading.
What is the magnetic field produced by this charge at the point?
The magnetic field produced by a charge at a point is the force exerted by the charge on a moving charged particle at that point.
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
How does a negative point charge behave in an electric field produced by a positive point charge?
A negative point charge will be attracted towards a positive point charge in an electric 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 is the relationship between the electric field produced by a point charge and a charged sphere?
The electric field produced by a point charge is directly proportional to the charge and inversely proportional to the square of the distance from the charge. For a charged sphere, the electric field outside the sphere behaves as if all the charge is concentrated at the center, similar to a point charge. Inside the sphere, the electric field is zero.
What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
What is the electric field produced by a single point charge in vacuum?
The electric field produced by a single point charge in vacuum is a force field that surrounds the charge and exerts a force on other charged particles in the vicinity. The strength of the electric field decreases with distance from the charge and follows the inverse square law.
What would happen if you placed a compass near an electromagnet when there is an electric current in the coil of the electromagnet?
The needle of the compass will align itself with the magnetic field produced by the electromagnet due to the flow of electric current in the coil. The compass needle will point in the direction of the magnetic field lines, which are generated by the current passing through the coil of the electromagnet.
What are three ways you can change the magnetic field produced by a current?
You can change the magnetic field produced by a current by altering the strength of the current flowing through the conductor, changing the direction of the current flow, or varying the distance between the conductor and the point where you are measuring the magnetic field.
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)

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)
