gravitation, gravitational attraction, gravitational force, gravity
(physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface
magnetic attraction, magnetic force, magnetism
attraction for iron; associated with electric currents as well as magnets; characterized by fields of force
van der Waal's forces
relatively weak attraction between neutral atoms and molecules arising from polarization induced in each particle by the presence of other particles
a chemical bond that involves sharing a pair of electrons between atoms in a molecule
a side bond that links two adjacent chains of atoms in a complex molecule
a chemical bond consisting of a hydrogen atom between two electronegative atoms (e.g., oxygen or nitrogen) with one side be a covalent bond and the other being an ionic bond

the gravity of the sun
magnetism produced by an electric current
magnetic field creates parallel but opposing spins; varies with temperature
phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a magnet
phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removed
materials like aluminum or platinum become magnetized in a magnetic field but it disappears when the field is removed
(physics) the influence that produces a change in a physical quantity
