MagnetsQuestions/Main Ideas Main Notes
Magnets always have _________________, a north pole and a south
pole
The earth is a magnet
How is Magnetism different from Electricity?
Magnets:
• North or South pole
• All magnets are __________, meaning all magnets have _________
(north and south)
1
Electric charges:
• + or –
• Charges can be alone (such as a lone electron)
How does Magnetism relate to Electricity?
• They cause each other!
• A moving magnetic field can induce a ___________
• A current (____________________________ charges) will produce a
______ field
Electromagnets
An _________________ is a type of magnet produced by the flow of electric
_____________
To find the magnetic field created by a current in a wire
Use your ___________ to determine the magnetic filed created by any
moving charge
• For a current in a ________ find the magnetic field by pointing your
thumb in the direction of the current. Curve your fingers; this is the
direction of the magnetic field.
Draw the direction of the magnetic field due to the conventional current in the wires
2
For a current in a ________ find the magnetic field by curving the fingers of
your right hand in the direction of the current in the wire. Make sure you line
your wrist up correctly! Your thumb points in the direction of the magnetic
field.
Draw the direction of the magnetic field due to the conventional current in the wires. Label the North and South Poles of the Electromagnet!

Magnetic Field and Causes of MagnetismQuestions/Main Ideas Main Notes
Magnetic Field
• Magnetic field lines start at a magnets _______ pole and end on
the ________ pole.
• Magnetic field lines are _______ together where the field is
_________ and get further apart as the field gets _________.
Causes of Magnetism
• Magnetic fields are created by ___________ charges
• Most materials have paired electrons _________ in opposite
directions
• The magnetic field created by one _________ electron is
__________ by the other
• Some materials, like _______, _____ and _______ are magnetic
because they have a single electron OR pair up electrons
spinning in the same direction
• The magnetic field created by one electron does ___________
the other!
• An atomic sized magnet is created!
4
• The atomic magnets line up to form a ____________
• When Domains line up in the same direction a magnet is formed
Circle the magnetic material!
When a magnet (dipole) breaks, does each piece of the broken
magnet have only one pole (monopole)?

Right Hand Rule Questions/Main Ideas Main Notes
Magnetic Force Use the right-hand rule to determine the direction of ________ a
______ will experience when it moves through a magnetic field.
Point your thumb in the direction of a conventional __________
the direction that a positive charge would move
Point your index finger in the direction of the __________ field.
Your middle finger will naturally reveal the direction of the ____
Draw a force vector showing the force the electric charge feels as it moves through the magnetic field
