It's called a deflection coil. If a c.r.t. uses magnetic deflection, there will be two deflection coils, a horizontal one and a vertical one.

What are the factors which influence the choice of specific magnetic and electric loadings of a synchronous machine?
The magnetic loading and electrical loading is most important parameter in the electrical machine. the electrical machine's torque is define as T=winding factor*electrical loading*magnetic loading*rotor volume You can see that the magnetic loading can decide electrical machines volume so this parameter is important.
How the direction can change of Permanent split capacitor motor?
A single speed permanent split capacitor AC induction motor has two separate pairs of series wound stator windings arranged at right angles to each other around the central rotor. The main run winding is connected directly to the AC power source while the secondary start winding is connected to the same source with a capacitor in series with it. The capacitor causes an electrical phase shift to the power in the start winding relative to the run winding, to produce a rotating magnetic field around the rotor which can start it turning. Since the capacitor remains in the circuit while the motor is running it's called a permanent split capacitor design.
What is the direction of the magnetic field if the current is directed upward or downward?
The direction of the magnetic field is counterclockwise or clockwise. For a current flowing in a wire you can use the "left hand rule" If you take your left hand and have the thumb point in direction of electron flow in the wire, the fingers wrapped around the wire will show the direction of the magnetic field by the direction the fingers are pointed..
Region around a magnet in which magnetic force can act?
Magnetic freild
What is produced around a wire that has a current?
Magnetic field.
How magnetic moment originate from motion of electron?
Electrons revolve around the nucleus. A revolving electron is equivalent to a current loop. Hence, it produces a magnetic moment.
What creates a magnetic charge within an atom?
The electron spin, and the electrons' revolution around the nucleus.
Is the Aurora Borealis a star?
no the Aurora Borealis is not a star. it is more commonly called the "northern Lights" the effect is when the magnetic field around the earth deflects the radiation from the sun. that is how the "light" effect is caused.
How magnetic moment of electron is associated with angular momentum of electron?
magnetic moment of a particle is due to its motion around some other orbits or about its own orbit i.e due to its orbital angular momentum or its spin angular momentum.
What is induction motor in physics?
An induction motor consists of a rotor winding and stator winding. Rotor windings are short circuited and stator winding are given electrical AC supply .Now lets do the physics behind it . As the current starts to flow in the stator winding , magnetic flux start to produce around it . due to it's alternating nature that flux varies and according to farady law emf is induced in the rotor winding .Since the rotor winding is short circuited the current circulates in it .And when a current carrying conductor is placed in magnetic field it experiances a force and hence if start to rotate.
How do you reverse a 1 phase motor?
turn it around A split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
What does the magnetosphere do to the solar winds?
It deflects the solar winds around the Earth
What do the parts of an electromagnet do?
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
What is the set up for a transformer that decreases the voltage on the out put side?
A basic, two-winding, transformer consists of two, separate, coils (called windings) wound around a laminated silicon-steel core. The winding connected to the supply (input) is called the primary winding, and the winding supplying the load is called the secondary winding. Alternating current flowing in the primary winding sets up an alternating magnetic field in the core which induces a voltage into the secondary winding. If there are fewer turns in the secondary winding, then the secondary voltage is lower than the primary voltage. If there are more turns in the secondary winding, then the secondary voltage is higher than the primary voltage.
What is Elctromagnetic?
An electromagnet is created by winding a coil of wire around an iron core. Electrical current is passed through the wire, which creates a magnetic field. Something that is electromagnetic is anything that is an electromagnet.
What is the relationship between electron and magnetism?
Electrons have a charge. Any moving charge creates an electric field, e.g. electricity moving through a wire causes a magnetic field around the wire, or the earth rotating creates a magnetic field which causes a compass to point north. Similarly all electrons have a spin factor. similar to the earth rotating, the spin of electrons create a magnetic field around the electron.
How does a transformation feel?
A transformer works on the principle of electromagnetic induction. Let's do a bit of review and then pull some things together. Any conductor through which current is flowing will have a magnetic field around it. When the current begins to flow, the field will build. Conductors with a changing current in them, with an alternating current (AC) flowing through them, will have a changing magnetic field around them. The field will arise and take form, then collapse. It will then arise again with the opposite polarity, and then collapse. This alternating field, which is a direct result of the alternating current, can be set up near another conductor to induce a voltage in that other conductor. The magnetic field around the first conductor is said to "sweep" the second conductor and induce that voltage in it. This is electromagnetic induction, and is the principle on which transformer action occurs. If we wind a coil of wire around a ferromagnetic core, the core will facilitate the "flow" of the magnetic field that arises as AC is applied to the winding. The addition of a second (secondary) winding around the core in the vicinity of the first (primary) winding will allow an optimum amount of "sweeping action" (magnetic coupling) to occur between the two windings. And if we tinker a bit with the number of turns in the windings, we can get stepped up or stepped down voltages as a result of the transformer action in the device.Transformer is a type of machine which is used to step up or step down the voltage.and works on the principle of mutual induction.according to which voltage can be induced in a winding that is electrically isolated from the winding connected with source...
