What does the ferromagnet become when it has domains aligned?
300
solenoid
A ____________ is a tightly wrapped coil in the form of a helix that can form a magnetic field.
300

Hans Orsted
This Danish physicist and chemist discovered that electric currents create magnetic fields, an important aspect of electromagnetism
500
solar power plant
This power plant is the only source that DOES NOT require a generator.
500
simple motor
What did we create when we created a solenoid hooked up to a battery with aligator clips with a magnet underneath
500
Water powers the turbine which provides the mechanical energy. The turbine is attached to the shaft which spins the generator, which turns the mechanical energy into electrical energy, which provides electricity to nearby neighborhoods.
Explain how a hydroelectric power plant works using mechanical and electrical energy in your description
