(1) Electric force does work on a rest or moving charge but magnetic force does only work on moving charge. 

(2) The electric force vector is along the direction of electric field $\vec E$, whereas the magnetic force is perpendicular to the plane of $\vec v-\vec B$. 

(3) The electric force can change the speed or kinetic energy of a particle but magnetic force can alter only the direction of the velocity of particle.
