Aligned dipoles refer to a configuration in which electric or magnetic dipoles are arranged in a specific orientation. This alignment can occur naturally in certain materials or be induced through external fields. The resulting collective orientation of the dipoles can lead to unique electromagnetic properties.

Are the attractive forces between polyethylene chains due to permanent dipoles or induced dipoles?
The attractive forces between chains are due to instantaneous induced dipoles, London dispersion forces,( not induced diipoles due to permananent dipoles). Polyethylene chains are long and the number of electrons is large- the intermolecular attraction will be significant.
Are dipoles in magnets?
Yes, magnets contain dipoles. In a magnetic material, each atom acts as a tiny magnet with a north and south pole, creating a magnetic dipole. These dipoles align in the material, resulting in a macroscopic magnetic field.
What are dipoles?
Dipoles means "two poles". This refers to molecules or anything where the ends have different charges or fields or polarities. A dipole magnet has a north and south pole. Dipole failure in insulation is where + and - charged pieces oscillate and cause the insulation to fail. Many molecules are dipoles.
What are the forces that depend on temporary induced dipoles known as?
The forces that depend on temporary induced dipoles are known as London dispersion forces or van der Waals forces. These forces are caused by the fluctuations in electron distribution around an atom or molecule, leading to a temporary dipole moment that can induce dipoles in neighboring atoms or molecules.
Is ClF4- polar or non polar?
There are two allowed structures of SF4Cl2... the cisform where one chlorine is in an equitorial position and one is axial, and the trans form where both chlorines are in axial positions. In the trans form the S-F bond dipoles all cancel each other, as do the S-Cl bond dipoles, because they are opposite each other. Therefore the molecule is non-polar. In the cisform, two of the S-F bond dipoles cancel, but because the other S-F bond dipoles are across from S-Cl bond dipoles, they do not cancel (S-F is more polar than an S-Cl bond). Therefore, the cisform is polar.
What are magnetic substances?
Magnetic substances are substances containing aligned dipoles. Dipoles are spinning electrons. In order for something to be magnetic, its dipoles must be aligned with each other, so that they face the same direction. The direction they face create a North end, while the opposite end creates a South end.Some substances, known as ferromagnetic substances, have permanently aligned dipoles. Other substances, such as paramagnetic and dimagnetic substances, require an external magnetic field to align, or 'induce' the dipoles of the substance.To conclude, magnetic substances contain dipoles which are permanently aligned, or can be aligned through the force of external magnetic fields.Diamagnetic Substances are those Substances there is no resultant field as the magnetic field produce by both the spin and orbital motions of the electrons might add up to zero.
what objects can be electrically polarized?
Objects that have asymmetrical distribution of charge, such as molecules with a permanent dipole moment or materials with aligned dipoles, can be electrically polarized. Examples include water molecules, certain crystals like quartz, and some ceramic materials.
What is hystersis loss?
As the emf in an AC circuit causes current flow in the core of an inductor the magnetic dipoles will align themselves with the direction of the flow. As the current reverses the dipoles tend to stay aligned and there is a certain amount of flow that is required to realign them in the opposite direction. Thus there is a lag between current reversal and dipole realignment. The energy used for this realignment so to speak is called hysterisis and is a loss to the circuit.
Are the attractive forces between polyethylene chains due to permanent dipoles or induced dipoles?
The attractive forces between chains are due to instantaneous induced dipoles, London dispersion forces,( not induced diipoles due to permananent dipoles). Polyethylene chains are long and the number of electrons is large- the intermolecular attraction will be significant.
What are the types of dipole?
The two main types of dipoles are electric dipoles, which consist of two opposite charges separated by a distance, and magnetic dipoles, which involve a pair of magnetic poles with opposite polarities. Electric dipoles are commonly found in molecules, while magnetic dipoles are seen in magnets and certain atomic particles.
What intermolecular forces are present in a molecule with no dipoles?
Van der Waals forces, specifically London dispersion forces, would be present in a molecule with no dipoles.
Are dipoles in magnets?
Yes, magnets contain dipoles. In a magnetic material, each atom acts as a tiny magnet with a north and south pole, creating a magnetic dipole. These dipoles align in the material, resulting in a macroscopic magnetic field.
Are all magnets man-made?
No, a magnetic field is induced by moving electric charges. If a ferrous material (one containing iron) is placed in a magnetic field, the individual magnetic dipoles can be aligned in accordance with the magnetic field. Since the molten iron in the earth's core carries charges, a magnetic field is induced around the earth (with field lines coming OUT of the south pole and into the north). This magnetic field can align magnetic dipoles just as any man-made electromagnet can.
What is magentism?
Magnetism is a phenomenon resulting from the movement of electric charges, typically seen in materials that have domains of aligned magnetic dipoles. These dipoles create a magnetic field around the material, which can attract or repel other magnetic materials. Magnetism is responsible for various applications, from compass needles aligning with Earth's magnetic field to the operation of electric motors and generators.
What is a kooman antenna?
A vertical array of horizontal full-wave dipoles that are driven by transposed two-conductor line and backed with a parasitic reflecting curtain or horizontal dipoles.
Is it grammatically correct to say aligned to or aligned with?
Both "aligned to" and "aligned with" are grammatically correct. However, "aligned with" is more commonly used when referring to things that are in agreement or in harmony, while "aligned to" is often used when referring to physical positioning or adjustment.
What are some example of iron?
Pure iron that has not been bonded with other substances such as aluminum or silicon. The presence of these substances keeps the magnetic dipoles (electrons, each of which acts like a tiny magnet due to its spin) aligned once magnetized and therefore the material remains magnetized. This does not occur in pure iron.
