The invisible area around a magnet where it can push or pull objects is called this.
What is a magnetic field?
The lines that show the direction and strength of a magnetic field are called these.
What are magnetic field lines?
Iron filings are often used in class to show these around a magnet.
What are magnetic field lines?
The Earth itself acts like a giant magnet because it has this inside.
What is Earth’s core?
Magnets have two ends called this.
What are poles?
Magnetic field lines always come out of this pole first.
What is the north pole?

The magnetic field of Earth protects us from this from the Sun.
What is solar wind?
Like poles of magnets do this when they are near each other.
What is repel?
Magnetic field lines are closest together where the magnetic force is this.
What is stronger?
This type of current creates a magnetic field around a wire.
What is electric current?
A compass needle points toward this, not exactly geographic north.
What is magnetic north?
Opposite poles of magnets do this when they are near each other.
What is attract?
A compass needle aligns with this to show the direction of Earth’s magnetic field.
What is a compass?
This simple device uses a coil of wire and a magnet to make electricity.
What is a generator?
Earth’s magnetic field is believed to be caused by movements in this layer.
What is the outer core?
