Radiation resistance of quarter wave monopole antenna is?
The radiation resistance of quarter wave monopole is 36.5 ohms
How will magnetic minerals align in a rock if earth has no magnetic field?
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
What is magnetic bearing?
It is a bearing (a direction) based on a magnetic compass reading.
What benefit does the magnetic field provide for people on Earth?
magnetic compasses
Why is the earth magnetic full detail?
The earth has a magnetic field which is similar to a magnetic bar tilted 11 degrees. This is caused because of the North and South pole.
What are magnetic monopoleswhen was the first monopole observed and by whom?
Magnetic monopoles are hypothetical particles that are predicted to exist with isolated north or south magnetic poles. The first potential observation of a magnetic monopole was reported by Blas Cabrera in 1982, using a superconducting detector. However, further research is still ongoing to confirm their existence.
Can you have a magnet with only one end?
Probably not. The magnetic monopole, as it is called, has never been observed. Some theories predict the possibility that they exist, though.
Differentiate between monopole and dipole?
A monopole is a single charge or magnetic pole that generates a field, such as an electric charge or a north or south magnetic pole. A dipole consists of two equal and opposite charges or poles separated by a distance, producing a dipole moment that creates a characteristic field pattern. In essence, a monopole has one pole, while a dipole has two poles.
What are the differences between a monopole and a dipole?
A monopole has one pole, while a dipole has two poles. Monopoles have a single charge or magnetic pole, while dipoles have both positive and negative charges or poles.
Do bar magnets have south and north poles?
Yes. All magnets of north and south poles. There is no such thing as a magnetic monopole.
Do black holes have a magnetic charge?
A black hole can have an electric charge if it swallows electrically charged objects, but no objects that we know of have magnetic charge. Magnets always have both a north pole and a south pole; there is no evidence that one can exist alone. A lone north or south pole would be called a magnetic monopole, and would have magnetic charge. If we discovered a magnetic monopole and fed it to a black hole then the black hole would gain the magnetic charge.
Magnetic field intensity of a straight conductor?
magnetic field is a region of space where a north magnetic monopole experiences a force. The direction of the field is by definition the direction of the force on the north end of a magnet. Since most texts contain diagrams of magnetic fields they will not be reproduced here.
Radiation resistance of quarter wave monopole antenna is?
The radiation resistance of quarter wave monopole is 36.5 ohms
Why do not exist magnetic monopole?
All magnetisim is due to moving charges. The best way to think of why all magnets have two poles is to think of a coil of wire with a current in it. This will create a magnet very much like a bar magnet. In the coil, one end is the North pole and the other end is the South pole. Now you can see that the coil must have two poles because it must have two ends. Cut the coil in half and it still has two ends. Cut the coil down to one loop and it still has two ends. Even in a bar magnet the magnetism is due to the orbiting electrons in the material. One side of the orbit is one pole and the other side is the other pole and there is no way to have an orbit without two sides. Now if magnetisim had magnetic charges ,like electricity does, then you could have magnetic monopoles but no one has ever found a magnetic charge.
Is pushing or pulling force that exist when a magnetic material is near?
Magnetic field
Magnetic charges exists really or is it a assumption?
No, magnetic "charges" do not exist -- magnetic POLES exist, and they exist always as a North-South pair, never separate from each other. If you break a magnet into pieces, each piece will itself be a magnet with N and S sides. The origins of this polarity is found at the atomic level and have to do with spin and orbital electron motions inside atoms. So an electron moving in its atom has both N and S poles. Which is the main difference when comparing to ELECTRIC charges: the positive and negative electric charges are carried by two different particles (the proton and the electron) and can be separated because the proton and the electron exist separate from each other. The magnetic POLES are both carried by the same particle, the electron, and thus do not exist on their own. (You cannot hold a N-pole in one hand and a S-pole in the other.) A lot of researchers have devoted loads of time trying to isolate a magnetic pole. (Looking for a "monopole.") Nobody has succeeded.
Do bar magnets have a north and South pole?
Yes. All magnets of north and south poles. There is no such thing as a magnetic monopole.
