Electric fields are described by Coulomb's Law, and they are fairly straightforward; like charges repel and opposite charges attract. Magnetism is more complicated, although it looks very similar, since like poles repel and opposite poles attract. But where as there are electric charges which generate electric fields, there are not magnetic charges that generate magnetic fields. Magnetic fields are actually created by electric charges, just as electric fields are, which is why electricity and magnetism are both aspects of electromagnetism rather than being separate forces. Spinning electrons generate a particular kind of electric force which, in combination with other spinning electrons, winds up creating forces that can be conveniently described as magnetic lines of force. But in reality, they are a form of electric force.
Physicists do theorize that there could be a particle called a magnetic monopole which generates its own magnetic force, rather than being dependent upon spinning electrons to do so, however no such particle has ever been detected and it remains purely theoretical.
Magnetic poles "are" electric charges, B=zD or Phi = ze where Phi is the magnetic pole in webers and z is the electromagnetic impedance and e the electric charge.
The charge is the generator of the pole and the spin of the charge determines the polarity.
An ion is a particle with only one charge, either positive or negative. A dipole has both.
magnetic dipole is not actually the monopoles separeted by some distance but a current loop, electric diople is actual concept.
Dipole refers a type of radio antenna. So, therefore, a folded dipole would be a radio antenna that is packed and ready for transport.
A dipole moment is a mathematical product of the magnitude of a charge and the distance of the separation between charges. There are also many other types of dipole moments, such as transition, molecular, bond and electron.
direction-along the axis of dipole from -q to +q.
There are three types of dipole. 1)Permanent dipole. 2)Instantenous dipole. 3)Induced dipole.
hydrogen, London dispersion, and dipole - dipole
A full-wave loop antenna can be interchanged with a folded dipole without much difference. The input impedance is similar and the only difference is in the directivity: a full wave loop radiates along the axis of the loop, while a vertical folded dipole is omnidirectional.
A folded antenna is a dipole type.
No it doesn't; as there is practically no difference in electronegativity between carbon and hydrogen to create a dipole.
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.
the existence of a dipole moment.
I don't think it has. Bandwidth depends on the diameter to length ratio of the antenna. The greater the diameter of the elements the wider the bandwidth. The inductance goes down and the capacitance goes up, giving the antenna a lower Q. the folded dipole has a greater effective diameter (at least double for the same materials). You can increase a normal dipole's bandwidth by increasing the diameter, hence the old time birdcage aerials.
An acetone molecule does have a net dipole. The dipole moment of acetone is 2.91 D. This is caused by the difference in electronegativity between methyl groups and a carbonyl group.
Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation
Yes, it does as there is a considerable electronegativity difference between given atoms.
The impedance of a centre fed dipole at resonance is about 73 ohms. The feed impedance of a folded dipole is four times that, 292 ohms. The feedpoint is of course balanced in both cases, thus 300 ohm balanced line is an excellent match for the folded dipole active element of a commercial TV antenna.
The interactions between HCl molecules is a dipole-dipole interaction.
