What are the three dimensions of light wave?
The three dimensions are the electric field, the magnetic field and the direction of the light.
What metal cannot be magnetized?
Non-ferrous metals do not contain iron(Fe) and are therefore not ferromagnetic. Most common of these are copper, silver, aluminium, lead, magnesium, platinum and tungsten. Magnetic fields can produce reactions in all materials, however, and these fall into three general categories: # Ferromagnetic materials, such as iron, cobalt, and nickel, which have a large positive magnetic susceptibility, and are capable of being magnetised by weak magnetic fields. # Paramagnetic materials, such as aluminum, magnesium, and platinum, which have a positive magnetic susceptibility due to molecules or atoms in which there are unpaired electrons, resulting in a magnetic moment contributed to by the spin or orbital motion of the electron. # Diamagnetic materials, such as copper, lead, and silver, which have a negative magnetic susceptibility caused by the motion of electrons in atoms around the nuclei, as they change their orbits and velocities to produce a magnetic field that opposes an applied field.
What is the zeeman effect?
The Zeeman effect is the splitting of single spectral lines into three or more in the presence of a magnetic field.
What are three parts of a wavelength?
There is one part to a wavelength - the wavelength, measured in metres.
How can a scrap heap magnets strength be increased?
There are three different ways to increase your magnet:Increase the voltage or current.Add more turns of the coil.Add a magnetic core inside the coils which will focus the magnetic field.
Name at least three magnetic metals from the periodic table of the elements?
to describe earth's magnetic field, there are three magnetic elements of earth listed as under, 1. angle of declination 2. dip 3. horizontal component of earth's magnetic field
What three elements do magnetic materials contain?
Magnetic materials may contain any mixture of certain elements. Three of the most common elements are iron, nickel and cobalt.
What are the three dimensions of light wave?
The three dimensions are the electric field, the magnetic field and the direction of the light.
What are the three characteristics of magnetic field produced by a current?
.
Do alloy stick on magnets?
The elements cobalt, nickel and iron are all magnetic. Most alloys containing at least one of these three elements will be magnetic. For example stainless steel is very magnetic. However alloys not containing these elements is most likely not magnetic.
Which device uses a rotating electric power source to produce a magnetic field?
well as the name mention production of magnetic field due to rotation. if we consider three identical coils axis physically by120* each and 3 phase supply given then their is the production of aleternating magentic field in each coil
What is the list for the characteristics of a magnetic field produced by a current?
A magnetic field is a change in energy within a volume of space. A magnetograph can be created by placing a piece of paper over a magnet and sprinkling the paper with iron filings. The particles align themselves with the lines of magnetic force produced by the magnet. The magnetic lines of force show where the magnetic field exits the material at one pole and reenters the material at another pole along the length of the magnet. It should be noted that the magnetic lines of force exist in three dimensions but are only seen in two dimensions in the image.
Why three phase induction motor has uniform torque?
The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.

What are the three elements that make up the Earths magnetic field?
The Earth's magnetic field is principally the result of electric currents generated in the mantle by its heat causing movement of this mass. A minor perturbation of this may be caused by currents derived from the Solar Wind - the flow of charged particles from the Sun. And of course the residual magnetization of local rocks will also have some effect.
What does a Rotating magnetic field do?
The Field which is continuously rotating with a particular axis is known as rotating magnetic field. It will be created in Three phase induction motor's stator. When the supply is given to stator of three induction motor, the flux of each phases (that are displaced by 120 degrees) will interact. Due to this the resultant Field will be rotating Magnetic Field will be Produced.
Why ozone is di magnetic?
There are three ways that matter is affected by magnetism: ferromagnetism, paramagnetism, and diamagnetism. Ozone is diamagnetic, meaning that it will try and move itself out of a magnetic field, and / or that a magnetic field will be weaker if ozone is present.
