When cathode rays are passed through a magnetic field which pole do they deflect towards north or south and why?
YahyaKerisvi
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.
Is Cesium a magnetic metal?
No, it is a diamagnetic metal but in gaseous form it is attracted towards magnet.
Is granite magnetic?
Granite can be slightly magnetic. If you bring rare earth magnet towards it, the magnet attracts. Especially if it is mined from India. Oxides of iron and titanium are responsible for this.
How does the declination change as you move north from where you live?
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.
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).
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 evidence that show cathode rays consists of charged particles?
in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.

Why cathode rays are negatively charged?
Cathode rays are produced when the metal cathode has a high voltage applied to it - this has the effect of "boiling" the electrons off the cathode's surface producing cathode rays, and so cathode rays can be seen as a stream of electrons i.e. negatively charged particles.AnswerElectrons are released from the surface of a cathode through thermionic emission. This is achieved by a heaterlocated at the cathode, and not due to a high voltage. The function of the high voltage (between the cathode and an anode placed closer to the screen) is to attract these electrons towards the screen of the CRT. So a 'cathode ray' is simply a beam of electrons which, of course, are negatively charged.
What is the sign convention for the cathode and anode in an electrolytic cell?
Anode is the positive electrode while cathode is the negative electrode. Negative ions(anions) travel towards the anode(hence the name) Positive ions(cations) travel towards the cathode(hence the name) Example for anode:Copper Example for cathode:Zinc
How did Thomson know that the electrons that he had discovered had a negative charge?
He devised a crook's tube with a near perfect vaccum with two aluminum plates in the center of the tube. One plate served as the anode to a circuit while the other served as a cathode, effectively creating a magnetic field between then with a negative field on one side and a positve field on the other. electrons (cathode rays) were then passed through, Because electrons are negatively charged, the negatively charged anode will repel them and force them to strike the florescent screen at a lower spot than if allowed to pass through freely. When the current it reversed the electrons strike the screen at a higher point than would normally occur
What effect will a positively charged metal plate have on a cathode ray?
Since a cathode ray is a stream of electrons, and since electrons are negatively charged, a positively charged metal plate would cause a deflection in the cathode ray towards the plate.
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.
In a cathode ray tube where do the particles originate towards what Do they move?
The particles originate from the Cathode in the neck of the tube. They are liberated by a heater. The electrons thus liberated are attracted by the Anode, by applying a high voltage to it. In a CRT there are several anodes, the largest and biggest is formed by a coating inside the tube towards the screen. This attracts and accelerates the electrons in a stream of particles known as a 'cathode ray'. They carry on in a straight line, once accelerated, until they hit the screen and cause a phosphor coating to glow, on the inside surface of the screen. The cathode ray can be bent from it's course, by using electromagnets arranged around the neck of the tube.
Why are anode rays called canal rays?
Anode rays are positively charged .so they are bend towards perforated cathode which is negatively charged and pass through them.since they have passed through canals or holes by producing fluorescence. Therefore they are known as canal rays.
How can a magnet be used to find direction?
basically in a compass is a needle which is magnetic. The magnetic field of Earth attracts the north pole of the magnet (which is the needle in the compass) to the north pole of Earth. Same thing goes for the south pole of Earth
