A device for deflecting the path of the beam. A magnetic dipole field bends the path charged particles (or beams of charged particles) with a force proportional to their velocity, the strength of the field, and the charge of the particles. An electric dipole field bends with a force proportional to the strength of the field and the charge of the particles.
Magnetized object that possesses north and south magnetic poles. A bar magnet and Earth are two examples.
Magnetic dipoles may be thought of as small bar magnets composed of north and south poles. Within a magnetic field, the force of the field exerts a torque that tends to orient a dipole with the field itself. Electric dipoles behave similarly in an electric field.
A molecule that has a positive end and a negative end.
a magnetic field characterized by its own north and south magnetic poles separated by a finite distance.
a pair of equal and opposite electric charges or magnetic poles separated by a small distance
a combination of partial positive charge and a partial negative charge located within a single structure
a covalent compound sharing two electrons in forming a bond between atoms
a molecule with a partial positive charge at one end and an equal but opposite negative charge at the other end
a molecule with two distinct polar ends (one more positive, one more negative)
a pair of electric charges ormagnetic poles of equal magnitude but opposite polarity, separated by some (usually small) distance
a pair of point charges, one with charge and the other with charge , separated by distance
a particle that carries a negative charge at one end and a positive charge at the other end
For oscillating magnetic fields, a magnetic particle that contains a *north* and *south* magnetic pole.
A system composed of two separated, equal, electric or magnetic charges of opposite sign.
a pair of equal yet opposite electrical charges that are separated by a small distance
A molecule which has a definite separation between its center of positive charge and center of negative charge. Such a molecule is said to be polar. A polar species will be more attracted to a charged species than will a non-polar one.
Two electric charges or magnetic poles that have the same strength but are opposite in sign or polarity (North versus South) and are separated by a relatively small distance.
A compact source of magnetic force, with two magnetic poles.
chem: polar molecule; phys.: electrically or magnetically charged particle with spatially separated positive and negative charge distributions
Dipole is a pair of separated opposite electric charges. Electric dipole is an assemblage of atoms or subatomic particles having equal electric charges of opposite sign separated by a finite distance. In the case of HCl, the electrons are attracted towards the more electronegative chlorine atom.
Equal positive and negative charges separated by a distance.
A magnetic field with a north and south pole, like that of a bar magnet.
A pair of separated opposite electrical charges.
Refers to the separation of charge between two covalently bonded atoms
Chemical compounds with an unequally distributed electric charge, such as the water molecule: the oxygen atom is of negative charge and the two hydrogen atoms are of positive charge. Dipolar molecules mutually attract each other. This is how water molecules connect into clusters via hydrogen bridges.
A pair of equal ges or poles of opposite signs.
1. System which has two equal but opposite electric charges or magnetic poles separated by a small distance. 2. Molecule with the centers of positive and negative charge separated. 3. Electrical set of poles with a switch, which can turn on two electrical lines simultaneously.
An asymmetrical distribution of electrical charge across an object. Polar molecules contain a dipole.
1. Without qualification usually means electric dipole, a system composed of two charges of equal and opposite sign separated by a distance. A magnetic dipole is an electric current loop enclosing a finite area in a plane. See dipole moment. 2. Same as dipole antenna.
