What is cross field?
a kick, pass, or ball that goes from one side of a sports field to another during a game.
What is the relationship between electric and magnetic fields?
Electricity and magnetism are two related phenomena produced by the electromagnetic force. Together, they form electromagnetism. A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current.
Can magnetic field cross?
Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end.
Is electric and magnetic field same?
Both electric and magnetic fields are the consequence of the attraction and repulsion of electric charges. However, a magnetic effect is caused by moving electric charges while an electric field is caused by stationary charges.
What is meant by Cross field in antenna?
A crossed field antenna (CFA) is a controversial type of radio antenna for long and mediumwave broadcasting, patented by F. M. Kabbary and M. C. Hately in 1986, which was claimed to have the same efficiency as a conventional antenna but only one-tenth the overall height.
Is electric force opposite electric field?
They experience the exact same electric force, just in opposite directions. An electric field that pushes in a charge will pull in the opposite charge. So, the electric force obviously has a direction.
What are the basic similarities and differences between an electric field and a magnetic field?
Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges).
What is electric field and magnetic field Quora?
An electric field is a field of force, surrounding a charged particle, while a magnetic field is a field of force surrounding a permanent magnet, or a moving charged particle.
What happens when magnetic fields cross?
If two field lines crossed, then that is saying that the magnetic field points in two different directions, at one place. Ordinary permanent magnets have North and South poles, and the magnetic field lines go out of the magnetic North pole and head towards the South pole, usually curving in the process.
Why do magnetic fields not cross?
The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.
What is the difference between electric field and electric field lines?
Electric field lines originate from positive charges and end on negative charges. The tangent to a field line at any point gives the direction of the electric field at that point. The lines are closer where the field is strong, the lines are farther apart where the field is weak. No two lines cross each other.
What is electric field in physics?
An electric field (sometimes E-field) is the physical field that surrounds electrically-charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to the physical field for a system of charged particles.
What are electric and magnetic fields?
Electric and magnetic fields (EMFs) are invisible areas of energy, often referred to as radiation, that are associated with the use of electrical power and various forms of natural and man-made lighting. EMFs are typically grouped into one of two categories by their frequency:
What is the motion of a charged particle in magnetic field?
The circular motion of a charged particle in the magnetic field The motion in a plane perpendicular to B is as before a circular one, thereby producing a helical motion. However, the electric field in y-direction imparts acceleration in that direction.
What is a uniform magnetic field used for?
A uniform magnetic field is often used in making a “momentum analyzer,” or “momentum spectrometer,” for high-energy charged particles. Suppose that charged particles are shot into a uniform magnetic field at the point in Fig. 29–2 (a), the magnetic field being perpendicular to the plane of the drawing.
How do electric charges produce magnetic fields?
A magnetic field is produced by an electric field because the e- are not static. One of best brief lecture (answer) on this I’ve found happens to be on StackExchange Physics (it is such a cool playground, not to mention Physics Forums ) How do moving charges produce magnetic fields? I recommend it and it is referenced for your further use.
