Jumble
Any material that attracts iron and materials
that contains iron
What is a magnet
Row 1, Col 1
What is, each end of a magnet
Magnetic pole
1,2
What is, a magnetic field
Spinning electrons
produce a ?
1,3
False - it is a magnetic domain
A grouping of magnetic
aligned atoms is known
as a magnetic field
1,4
What is, proton, neutron, electron
Particles found in an atom
2,1
What is, at the two poles
Where you would find the
strongest magnetic field on a
magnet
2,2
What is, making, destroying and breaking
Magnets can be
changed by---
2,3
True
The geographic pole of the Earth
is not the same as the Earth’s
magnetic poles
2,4
What is, solar wind
A stream of electrically
charged particles flowing
at high speeds from the
sun
3,1
What is, magnetic field lines
Spreads from one pole,
curves around the magnet ,
returns to the other pole
3,2
What is, the magnetic domains point in
random directions
A material is not
magnetized.
Describe it’s
magnetic domain
3,3
False, protons have a positive charge
An electron is a particle
that carries a positive charge
3,4
What is, hardened molten rock on the oceans
floor provides a record of the Earth’s
magnetic field over time
Evidence which shows
that Earth’s magnetic field
changes?
4,1
What is, a south magnetic pole or unlike pole
A north magnetic pole
is attracted to_________
4,2
What is, domains are arranged in the same
direction in magnetized material
Domains in magnetized
material are arranged in______
4,3
False, each piece of the magnet retains its
magnetic properties
When a magnet is cut
in half, it is no longer magnetized.
5,4
What is, an aurora
A glowing region in
the atmosphere caused
by charged particles from the sun
5,1
What is, magnetic field lines leave the north
pole and enter the south pole
Indicate the direction of
magnetic field lines
5,2
What is, an increase in the magnetic field
The result of the overlap
of two or more
magnetic fields
5,3
True
The angle between geographic
north and the north to which
a compass needle points is
known as magnetic declination
4,4
Final Jeopardy
Describe the magnetosphere,
include 3 details about its shape
Final Jeopardy
•What is, the region of the Earth’s
magnetic field
•Shaped by the solar wind
•Constantly reshaped by solar wind as
Earth rotates on its axis
•Solar wind causes magnetosphere to
stretch out on the side of Earth not facing
the sum
