draw different types of artificial magnet ?
Here are some of the common types available for performing your experiments.
This is a small disk NIB magnet, about 0.50" diameter, 0.125" thick.

This is a kidney shaped NIB magnet, about 7/8" by 0.50", 0.10" thick.
Arbor , Scientifics Online , AS&S 29079, EdIn M-150
This is a trapezoidal shaped NIB magnet, about 1.25" by 0.75", 0.375" thick. These are very powerful!

These are several marble magnets, each about 0.5" diameter.
Arbor P8-1122, Scientifics Online 34-968, AS&S , EdIn M-620
This is a wand ceramic magnet. They are quite strong, great for experimenting .
Arbor P8-1165, Scientifics Online , AS&S , EdIn M-510
This is a real alnico cow magnet.
Arbor , Scientifics Online 31-101, AS&S , EdIn M-400
These are an assembled cow magnet.
Arbor , Scientifics Online 52-490, AS&S , EdIn M-450
This is an alnico horseshoe magnet. Please note the keeper on the end of the magnet, which helps to prevent the magnet from becoming demagnetized.
Arbor , Scientifics Online , AS&S , EdIn
This is a long, narrow alnico bar magnet.

This is a slightly flexible ceramic or ferrite disk magnet. Not very strong, but not likely to chip, either.
Arbor , Scientifics Online , AS&S , EdIn
This is a ferrite bar magnet. Quite strong.
Arbor , Scientifics Online , AS&S , EdIn
This is another ferrite bar magnet, actually, more like a block or brick! On both of these ferrite magnets, you can see little chips missing along the edges. This happens when they are allowed to come together quickly.

This is a string of 100 spherical magnets that stick to each other. These are a lot of fun to play with - just not good for small children. You can make a necklace, bracelet, ring, coils - all sorts of shapes. These are 1/4" in diameter, and have a black nickel finish. They were from K & J Magnetics, and cost about $60.
