Magnetism
Magnetic Field
Strongest at the Poles
Earth's North Pole= : Magnetic South Pole {Vice Versa}
Symbol: B SI Unit is T(Tesla)
Produces Vector Field
Magnetic Lines form a curve around the field
Magnets
Consist of Two Poles
North
South
Monopole (Doesn't exist): one pole
Attraction/
Repulsion
Like Poles Repulse
Opposite Poles Acttract
Material Reactions
Ferromagnetic
Strongly Attracted [Iron, Cobalt, Nickel]
Diamagnetic
Repelled By Magnets [Glass, Rubber, Wood]
Paramagnetic
Weakly Attracted [Aluminum, Oxygen, Sodium]
Domain
Magnetized: Arranged Direction
Unmagnetized: Random Direction
Groups of Atoms with Aligned Poles
Right Hand Rule
Finger = Direction of Magnetic Field
Palm = Direction of Force
Thumb = Direction of Particle
Forces
Experienced by moving charge in the field
F= qvBsin(theta)
q = Charge
v = Velocity
B = Magnetic Field
