Magnetism | Magnets occur naturally in certain substances. A magnetic substance will produce a magnetic field that can attract or repel certain objects. |
Electromagnets | Electromagnets are an important part of generating electricity for everyone. |
Generator | A generator is a device that produces an electric current. Inside a generator is a coil of wire. A iron core is rotated inside the coil of wire using a turbine. A turbine is a fan blade that is turned by wind, water, or steam. |
Electric Motor | An electric motor transforms electrical energy to kinetic energy. In an electric motor, an electromagnet makes a coil of wire spin. |
