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.
Dipoles are molecules that have both a positive and a negative charge at opposite ends, creating a separation of charge. This occurs when there is an uneven distribution of electrons, leading to a partial positive and partial negative charge on different ends of the molecule. Dipoles are important in various chemical and physical interactions, such as in solubility, intermolecular forces, and chemical reactions.

What is aligned dipoles?
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 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 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.
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 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.
What causes dipoles attractions?
The attraction between polar molecules.
How might a molecule with two strong bond dipoles have no molecule dipole at all?
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a large dipole moment. However, because one dipole points to the left and the other points to the right, the dipoles cancel and overall there is no molecular dipole.
How might a molecule with two strong bond dipoles have no molecular dipole at all?
If the two strong bond dipoles are arranged symmetrically in opposite directions within the molecule, their effects can cancel each other out resulting in a net dipole moment of zero. This can occur in molecules with a linear or symmetrical shape, where the bond dipoles are pointing in opposite directions and their magnitudes are equal.
What is a yagi?
A yagi is a directional antenna consisting of two or more 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.
Are induced dipoles permanent?
Induced dipoles are temporary and not permanent. They are created in nonpolar molecules when they are exposed to an electric field, causing the distribution of electrons to shift temporarily, resulting in the formation of a dipole moment. Once the electric field is removed, the induced dipoles disappear.
Do London dispersion forces exist between polar molecules and result from temporary dipoles?
Yes, London dispersion forces can exist between polar molecules because all molecules, polar or nonpolar, can have temporary fluctuations in electron density that create temporary dipoles. These temporary dipoles can induce similar dipoles in nearby molecules, leading to London dispersion forces even in polar molecules.
