Magnets
This is generated when a bar magnet is moved through a wire coil.
What is electric current
The plate boundary between two plates moving together.
Convergent boundary ඞ
The top of a wave.
What is the crest?
This object uses mechanical energy to produce electricity.
What is an electric generator
These are created when two convergent plates collide.
What is mountains, island arcs, volcanoes and ocean trenches.
How often the particles of the medium vibrate when a wave passes through the medium
What is frequecny?
This is created from a coil wire wrapped around an iron core connected to an electric current.
What is an electromagnet
These tides occur when there is a new or full moon.
What is spring tides
The two types of waves.
What is longitudinal and transverse waves?
This is how you increase the strength of an electromagnet without adding more coils.
Increase the electric current.
This is the thickest layer
What is the mantle?
The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
What is wavelength?
The Earth is like this kind of magnet.
What is a bar magnet.
This is the most dense layer.
What is the inner core?
The bottom of a wave.
What is the trough?
