It's Electric!
A physical property of matter that either attracts, repels, or remains neutral when interacting with other objects.
A force that pulls an object towards it.
What is attraction?
True or False:
You must have a complete cycle of connection to form a complete circuit.
What is true?
What is a magnetic field?
Without this the copper coil will not become an electromagnet and a speaker cannot work.
What is a power source (energy source)?
The flow of power or charge.
What is electricity?
A force that pushes an object away from it.
What is repulsion?
This happens to the plastic cup when too much power from the battery is running through the copper coil.
What is it melts?
An object that attracts or repels certain types of metal.
What is a magnet?
Adding this to a speaker set-up helps to increase the volume of the sound it generates.
What is an amplifier?
What is vibrate?
This is what happens to the compass needles when you place them around a magnet.
What is the needle points towards the magnet?
This is what happens to the electric current when you reverse the position of the battery in a circuit.
What is it changes direction?
This is what you create when you add electricity to copper wire.
What is an electromagnet?
The more energy you put into a speaker, the ______________ the sound that is produced.
What is louder?
This is how wireless devices connect/communicate with each other.
What is Bluetooth or WiFi?
In a gyroscope, the compass needle points towards this direction.
What is True North?
You need to do this to the speaker set-up to make the sound louder.
Lodestone is an example of this type of magnet.
What is a permanent magnet?
The type of energy that a ball has while it is rolling down the hill (in motion).
What is kinetic energy?
This non-metal material is an excellent conductor of electricity. (Hint: it's in our bodies)
What is water?
This is what happens to the magnetic fields of 2 magnets when you place a north/north together or a south/south together.
What is they move away from each other (repel)?
Wires, speaker, sound source, ______________.
What is a battery or power source?
Maglev trains do this with the help of electromagnets.
What is levitate?
The type of energy that a ball has when it is sitting on top of a hill (not moving).
What is potential energy?
