if electric field is used then we have to apply a very high voltage ,or we may require a very long tube.however ,if a magnetic field is used ,even a small field can produce large deflection ,on the other hand ,the required size of the picture tube will be highly reduced .due to this reason,the magnetic field is uesd to deflect the electron beam in T.V. insted of the electric field.

An electric current can be used to deflect a compass needle. When an electric current flows through a conductor, it generates a magnetic field around it, which can interact with the magnetic field of the compass needle, causing it to deflect. This principle is the basis for electromagnetism.
When an electric current flows through a wire, it creates a magnetic field around the wire. If this wire is placed in the presence of another magnetic field, the two fields can interact, causing the wire to deflect. This phenomenon is known as the magnetic deflection of an electric current.
Yes, an electric current can generate a magnetic field that can deflect a compass needle. This phenomenon is known as electromagnetism and is the basis for how devices such as electromagnets and speakers work.
Yes, an electric current can create a magnetic field that can deflect a compass needle. This phenomenon is known as the Oersted Effect and demonstrates the relationship between electricity and magnetism.
four coils are used to create a magnetic field to deflect the electron beam in two dimensions.

Magnetic lenses are used to control the electron beam in an electron microscope. The magnetic field produced by the magnetic lenses deflects the energetic electrons. They are typically called magnetic lenses because they deflect the electron beam like optical lenses deflect light.

CRT style televisions use an electromagnet, called the "Yoke", on the neck of the CRT in order to deflect the electron beam.
A current-carrying wire generates a magnetic field around it due to the flow of electric charges. When the wire is placed near a magnetic compass, the magnetic field produced by the wire interacts with the magnetic field of the compass needle, causing the needle to deflect and align with the direction of the wire's magnetic field.
Put a wire carrying an electric current near a compass and it causes the needle to deflect.
Yes, electromagnetic waves can be deflected by electric or magnetic fields. The direction and magnitude of the deflection depend on the orientation and strength of the field relative to the direction of the wave propagation. This phenomenon is the basis for technologies such as antennas and magnetic resonance imaging (MRI).
Yes, an electric current can affect a compass needle because it creates a magnetic field. When the electric current flows through a wire, it generates a magnetic field around the wire, which can deflect the compass needle and change its direction.
