Magnetic Materials
Iron,Nickel,Cobalt
Poles in relation to Magnetic and Geographic
Magnetic North = Geographic South
Magnetic South = Geographic North
Magnetism
A physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between magnetic objects
4 clues that something is magnetic
- Magnetizing and Demagnetizing
- Made of Iron, Nickel or Cobalt
- Hard and Soft Magnetic Material
- Moving Charge makes Magnetism
How do you detect the shape of field lines
another magnet, free to rotate will line up with the field line it is on and give it a direction. This free magnet is called a plotting compass
when Combining magnetic fields, things to remember
field lines always go from N to S, but consider which is the nearest south
field lines can’t cross but they can join
Definition : Magnetic Field
A magnetic field is the region around a magnet ( or a moving charge ) where another magnetic material is affected by a force.
Poles : Magnetic
Poles : Gravity
Poles : Electric
Magnet Field Lines for 1 magnet, 2 attracted magnets and 2 repelling magnets
draw and compare in book
Which way would a compass point
