  We report on experiments with cold thermal $^7$Li atoms confined in combined
magnetic and electric potentials. A novel type of three-dimensional trap was
formed by modulating a magnetic guide using electrostatic fields. We observed
atoms trapped in a string of up to six individual such traps, a controlled
transport of an atomic cloud over a distance of 400$\mu$m, and a dynamic
splitting of a single trap into a double well potential. Applications for
quantum information processing are discussed.
