How magnetic field is related with cathode rays in physics?
Cathode rays are negatively charged particles that move in curved paths in the presence of a magnetic field. The direction and curvature of the cathode rays can be controlled by adjusting the strength and orientation of the magnetic field. This phenomenon is known as the magnetic deflection of cathode rays and is used in devices like cathode ray tubes.
How did Thomson determine that cathode rays are negatively charged?
Thomson observed that cathode rays were deflected by electric and magnetic fields in a manner consistent with them having a negative charge. He measured the charge-to-mass ratio of cathode rays and found it to be the same regardless of the material used for the electrodes, which suggested the charge was a fundamental property of the particles themselves.
Why Cathode rays travel in straight lines?
Cathode rays travel in straight lines because they are composed of charged particles (electrons) that are negatively charged, and they are repelled by like charges. This repulsion causes the cathode rays to travel in straight paths from the cathode to the anode in a vacuum tube without deviating from their path.
What evidence convinced Thomson that cathode rays consist of negatively charged particles?
In a series of experiments in the 1890's, J.J.Thompson showed that cathode rays, or electrons, are deflected by an electric field, they are bent by a magnetic field, and that their charge to mass ratio is about 1/2000th of that of the proton. Light does not have any of these properties.
Can x rays be affected by magnetic fields?
Yes, X-rays can be affected by magnetic fields. When passed through a magnetic field, the path of the X-rays can be altered, leading to changes in the resulting image or data obtained. This effect is known as the Faraday effect.
What did john Thomson use to deflect the cathode rays?
he dint did nething to deflect them thet went straight to the anode +ve of the tube becoz opposite attracts.

What did Thomson use in his experiments?
J.J. Thomson studied the deflection of cathode rays in electric and magnetic fields.
By measuring the deflection of cathode rays in electrical and magnetic fields J.J. Thomson was able to determine what?
J.J. Thomson was able to determine the charge-to-mass ratio of an electron by measuring the deflection of cathode rays in electrical and magnetic fields. This discovery led to the identification of electrons as fundamental particles in atoms.
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 rays in the cathode ray tubepositive or negative or neutral?
The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.
How do cathode rays form?
Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
Which scientist discovered that cathode rays are made up of negatively charged particles?
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
Why cathode ray are not electro-magnetic waves?
A cathode ray is a stream of electrons, not a stream of photons like the electromagnetic wave. It's a different type of particle. The electrons don't move at light speed in a vacuum; also, they are electrically charged.
Do magnetic fields affect X Rays?
No, magnetic fields do not affect X-rays. X-rays are a form of electromagnetic radiation, while magnetic fields affect charged particles. Therefore, magnetic fields do not interact with X-rays in the same way they do with charged particles.
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.
