Physics 7.1.2 Flashcards
Magnetic Materials are Attracted to a…
Magnet.
Non-Magnetic Materials are Non Attracted to a…
Magnet.
What are some Common Magnetic Elements? (3)
-Iron.
-Cobalt.
-Nickel.
Why is Steel Magnetic?
Steel is an Alloy which Contains Iron, so it is Also Magnetic.
Magnetic Materials (which are Not Magnets) will Always be ___ to the Magnet, regardless of…
Which Pole is held Close to it.
What Should you do to Test whether a Material is a Magnet?
It Should be Brought Close to a Known Magnet.
What will Tell you that an Object is a Magnet?
If it Can be Repelled by a Known Magnet, then it itself is a Magnet.
What will Tell you that an Object is Not a Magnet?
If it Can Only be Attracted & Not Repelled, then it is not a Magnet; it is a Magnetic Material.
What are the 2 Types of Magnets? (2)
-Permanent Magnets.
-Induced Magnets.
What are ‘Permanent Magnets’?
Permanent Magnets are Made out of Permanent Magnetic Materials, eg Steel.
A Permanent Magnet Will…
Produce its Own Magnetic Field.
A Permanent Magnet Will Not…
Lose its Magnetism.
What is an ‘Induced Magnet’?
When a Magnetic Material is Placed in a Magnetic Field, the Material can Temporarily be Turned into a Magnet.
Magnetic Materials will Always be ___ to a Permanent Magnet.
Attracted.
The End of the Material Closest to the Magnet will…
Temporarily have to Opposite Pole to the Pole of the Magnet held Closest to it. EG if the left side of a paper clip is held near the North Pole of a Magnet, the left side of the paper clip Temporarily becomes a South Pole, so that is Attracts to the Magnet’s North Pole.
