Studying tool

Generator, motor, energy, electromagnets, magnetism, etc.

What does a generator do? Uses mechanical energy to produce electrical energy
What do generators produce? Electric currents when the coil of wire is wrapped around an iron core and is rotated near a magnet
How does a generator produce electricity? Are power plants that ________ for homes and businesses. Turbines are huge wheels that rotate when pushed by water (hydroelectricity), wind (windmill), steam (fossil fuels, nuclear, geothermal)
What is an electromagnetic? Is formed when a wire in an electric current is wrapped around in an iron core producing a magnetic field. The strength will increase with additional wraps.
What is magnetic field? Surrounds a magnet and exerts a magnetic force on other magnets
What is a simple electric motor? Turns electrical energy into mechanical energy. It contains an electromagnet that rotates between the poles of a magnet.
What do like poles do? Repel
What do unlike poles do? Attract
When an electric current flows through the wire in the electromagnet, a magnetic field is produced, where? In the coils
What is a magnetic domain? Group of atoms whose fields point in the same direction
What is magnetism? A force of attraction and repulsion of magnetic material (iron, cobalt, nickel).
What are the strongest parts of the magnet? The poles
