Study of magnets |
Magnetism |
|
|
4 Properties of Magnets |
1. Attracts material that are magnetic in nature 2. Like poles repels, unlike poles attract 3. When allowed to hang freely magnets aligns in one particular direction 4. Magnetic poles always occur in pairs |
|
|
2 types of material |
Magnetic Non-Magnetic |
|
|
Property of a magnetic material |
Alligned atoms |
|
|
Property of a non-magnetic material |
Randomly arranged atoms |
|
|
3 types of magnetic material |
1. Ferromagnetic 2. Paramagnetic 3. Diamagnetic |
|
|
Properties of ferromagnetic magnet |
-Strongly magnetize -many vacant |
|
|
Properties of paramagnetic magnet |
-Weak -1 vacant |
|
|
Properties of diamagnetic magnet |
-closer to 0 -no vacant |
|
|
2 types of ferromagnetic magnet |
Soft Hard |
|
|
Properties of SOFT ferromagnetic magnet |
Easily attracted but easily demagnetized |
|
|
Properties of HARD ferromagnetic magnet |
Not easily attracted but once attracted magnetism last forever |
|
|
Factors that can demagnetize a magnet |
1. Heated 2. Fell (Nahulog) 3. When attracted to a bigger magnet |
|
|
When a pole is POSITIVE/NORTH the magnetic field points |
Away from the magnet |
|
|
When a pole is NEGATIVE/SOUTH the magnetic field points |
Towards the magnet |
|
|
The magnetic field at the poles are ___________. |
Stronger |
|
|
The magnetic field at the middle is ___________. |
Weaker |
|
|
The geographical north is the _______________. |
Magnetic south |
|
|
The geographical south is the _______________. |
Magnetic north |
|
|
When a magnet is split into two what happens |
Both magnets will still have north and south poles because magnets are not monopole |
