subject: What are Permanent Magnets and How do They Work? [print this page] Generators as well as motors are another big area of utilization of magnets. Huge magnets are used to generate electricity at hydroelectric power station. Actually the stored water at the dams is fallen on the turbines at the power station. Due to the kinetic energy of water the turbines rotate and these turbines are connected to the coils. These coils rotate in huge magnetic frames. Due to the magnetic fields around, these rotating coils produce electric current. This electricity is then supplied to the power stations. Thus magnets play a vital role in our day to day life.
