Electricity is the presence and flow of electric charge (electrons) in one direction. The best known form of electricity is the flow of electrons through conductors (ex. copper wires). Electricity can mean "electrical energy". Magnetism is one aspect of the combined electromagnetic force. Magnetism refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects. The motion of electrically charged particles gives rise to magnetism.
