When cathode rays are passed through a magnetic field which pole do they deflect towards north or south and why?
Cathode rays are electron beams. When they are moving in a magnetic field, they are deviated. The direction of their deflection is given by Fleming's left hand rule. The direction of deflection, current (which is the reverse of the direction of the electron beams) and field are all perpendicular to each other. Hence, the electron beam will deviate in a direction contained in a plane which is perpendicular to both the field and the electron beam.
Hence, the cathode rays are neither defleted to the north nor south pole.

Is iron magnetic or not?
Iorn is magnetic. when we take a magnet towards iorn fillings the fillings get attracted towards it .hence iorn is magnetic
What pulls the South Pole of a magnetic compass?
The south pole of a magnetic compass is pulled towards the Earth's north magnetic pole, and away from Earth's south magnetic pole. Or towards and away the corresponding poles of any other magnet. Note that Earth's NORTH magnetic pole is close to the SOUTH pole.
What happens when electricity is passed through sodium chloride?
When electricity is passed through sodium chloride (NaCl) in a process called electrolysis, the compound breaks down into its component elements: sodium (Na) and chlorine (Cl). Sodium ions migrate towards the negative electrode (cathode) and gain electrons to form sodium metal, while chloride ions migrate towards the positive electrode (anode) and lose electrons to form chlorine gas.
A device that uses the Earths magnetic field to indicate witch way north is?
A compass is a device that uses the Earth's magnetic field to indicate which way is north. It aligns with the Earth's magnetic field, with one end pointing towards the magnetic north pole and the other end pointing towards the magnetic south pole. This allows users to determine their direction and navigate accurately.
The south pole a compass magnet points toward?
magnetic north north pole =magnetic south
Do the rays produced in cathode tube deflect towards negative plate?
The electron beam produced in the cathode is essentially negative (with respect to the anode), therefore it tends to go towards potentials above the cathode's potential (more positive or less negative, as you wish).
How do negatively charged plates affect the path of cathode rays?
Negatively charged plates will attract cathode rays, causing them to bend or deflect towards the plates. The extent of the bending will depend on the strength of the electric field between the plates and the voltage applied across them.
What is the opposite to a cathode?
A cathode is an electrode through which electrical current exits a polarized electrical device. Its opposite is the anode, through which electrical current enters the electrical device. Positively charged ions, called cations, move towards the cathode, while negatively charged ions, called anions, move towards the anode.
What is the ion release in between cathode and anode?
Ions are released at the anode during oxidation, and they move towards the cathode through the electrolyte. At the cathode, the ions gain electrons and are reduced. This process results in the transfer of ions between the cathode and anode.
Why the magnetic needle gets reflected when placed near a current carrying wire?
The magnetic needle gets deflected near a current-carrying wire due to the magnetic field generated by the current. The magnetic field induces a force on the needle, causing it to align or deflect towards or away from the wire. This phenomenon is a result of the interaction between the magnetic field and the magnetic properties of the needle.
How do electromagnets pull?
Electromagnets pull objects towards them by creating a magnetic field when an electric current passes through them. This magnetic field attracts objects made of magnetic materials, causing them to be pulled towards the electromagnet.
What is the function of anode in cro?
In a cathode ray oscilloscope (CRO), the anode serves to accelerate the electrons emitted by the cathode towards the screen at the other end of the tube. This acceleration helps to produce a focused beam of electrons which can then be deflected by the electric or magnetic fields to create an image on the screen.
How were electrons produced from the cathode ray ube?
Electrons were produced in a cathode ray tube by applying a high voltage to the cathode, causing electrons to be emitted through thermionic emission. These electrons were then accelerated towards the anode by the electric field within the tube, creating a beam of electrons known as the cathode ray.
What is the evidence that show cathode rays consists of charged particles?
One piece of evidence is the observation that cathode rays are deflected by electric and magnetic fields, indicating they carry charge. Further evidence comes from the fact that cathode rays produce X-rays when striking a target, which is consistent with the behavior of charged particles like electrons. Additionally, the ratio of the charge to mass of the particles in cathode rays was found to be the same as that of electrons.
What are the factors that affect for deflection of cathode rays towards magnetic and electric field?
The electron is a charged particle and can be attracted and repelled by a magnetic field. In a CRT the magnetic field is generated by coils around the neck of the tube. A voltage applied to the coils,will turn them into electromagnets. The coils are supplied with a varying voltage from electronic circuits. The waveform is usually a 'sawtooth', which rises slowly and then returns to '0' rapidly. This will cause the electron beam to move across the screen and then return back to the beginning. Two sets of coils are provided horizontally and vertically. This arrangement allows for the beam to scan across the screen, producing lines, moving progressively downward, making a field.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
Is it true that Electrons were discovered when an electric current was passed through gases at low pressures?
Yes, Sir J.J.Thompson did exactly that. ( although at that time the terms used for these phenomena were different). In 1897, Thompson heated a metal to produce cathode rays or electrons. These electrons were attracted towards an anode by providing a potential difference between the two electrodes. Between the cathode and electrode was air at very low pressure which did not stop these cathode rays. Sir Thompson studied these beams in the space between the anode and cathode.
