Magnets
Demagnetising a magnet
Dropping it repeatdly
Heating it up
Hitting it repeatedly
Poles of magnets
North Pole
Labled RED on most magnets.
Attracted to the South Pole of other magnets.
Repelled by the North Pole of other magnets.
Attracted to magnetic materials but cannot repel them.
South Pole
Labled BLUE on most magnets.
Attracted to the North Pole of other magnets.
Repelled by the South Pole of other magnets.
Attracted to magnetic materials but cannot repel them.
Creating a TEMPORARY magnet
Stroking method
Stroke the magnet with the magnetic object IN THE SAME DIRECTION about 50-100 times. Then, test it out by placing it near some paper clips.
Slower method
Does not require any electricity
Increasing magentism
Stroke more times
Use a stronger magnet
Electrical method
Requires use of electricity
Arrange two batteries in the RIGHT ORDER, connect the wire to the batteries and coil it around the magnetic object. Then, put some paper clips near the object.
Faster method
Increasing magnetism
Increase the number of coils around the object.
Add more batteries.
Magnetic vs non magnetic materials
Magnetic materials
Iron, Steel, Cobalt, Nickel, Alloys
Acronym for remembering: I (iron) Always (Alloys) Steal (Steel) Chicken (Cobalt) Nuggets (Nickel)
Allows magnetism to pass through
Could be made into temporary magnets
Non-Magnetic materials
Cannot be made into temporary magnets
All other materials
Does not allow magnetism to pass through
