<p>An electromagnetic pump comprises a cylinder (20), a piston (30), a first induction coil (40), a second induction coil (50), and a magnetic housing (60). The piston (30) is slidably disposed in the cylinder (20). The first induction coil (40) and the second induction coil (50) are fitted over two ends of the cylinder (20) and are alternately provided with a power source to effect an excitation. The piston (30) is caused by the excitation to move linearly back and forth within the cylinder (20), thereby enabling the piston (30) to draw in fluids and to force out the fluids.</p> |
