All matter is made up of particles that have ______ _______ (2 words).
Electric charges
What is the name of the closed path that electric current flows along?
Electric circuit
These are types of materials where electricity can flow easily.
Electrical conductors
An electric current produces a magnetic field so it means that we can make magnets using electricity. They consist of an iron core surrounded by a coil of wire. What is this called?
Electromagnets
The magnetic north pole of the Earth is in the ______.
South
What are the two types of electric charges?
Positive and negative
Electricity flows from an _______ ______ (2 words. Example: battery)
Energy source
Electrical insulators
Give an example of an object that uses electromagnets.
Computers, doorbells, magnetic cranes
loudspeakers, headphones, MRI machines, motors, VCRs, microphones, telephones, hairdryers etc
It is a part of an electric circuit that opens and closes the circuit.
Switch
Objects with opposite charges _______. They pull towards each other.
attract
True or false: when the switch is on, the circuit is closed.
True.
These are objects that attract other objects made of the same material.
Magnets
True or false: the magnetic field of electromagnets can't be switched on or off.
False
The electric current flows along a ________ or a _________.
Wire or cable
This type of electric charge can move from one object to another.
Negative charge
Electric current flows in a closed circuit without interruption to reach a ______.
device
It is a non-contact force that works at a distance.
The magnetic south pole of the Earth is in the _____.
North / geographic North Pole
True or False: when an object loses negative charges, it becomes negatively charged.
False. It becomes positively charged.
electric current
When negatively charged particles pass from one object to another, it creates an imbalance of electric charges. What is this kind of electricity? (ex: it makes your hair stand up)
Static electricity
It is a natural magnet found in the ground.
Magnetite
It is an object that uses the Earth's magnetic field to find directions.
Compass
Electricity is produced at ______ ______ using different energy sources.
Power stations
