ferrous materials
Ones that contain IRON
The field lines would leave one pole (end of the magnet) and then curve around one side to come back to the other pole in kind of a semi-oval. Picture two ovals side by side, then picture the bar magnet placed between them, overlaying the long edges of the ovals where the ovals touch. This can be observed by pouring some iron filings onto a piece of paper and then placing a bar magnet underneath the paper. The filings will line up along the field lines providing a visual picture.
copper
electrical energy
Boron can be found in a regular magnet (like in [or on] your refrigerator).
what kind of magnet is a magnetized nail
Sewing supply shops do sometimes carry bars with handles that are made of magnet. These are generally used for situations like these. Otherwise, you could use anything that has a strong (at least kind of) magnet, such as magnetic scissors or a strong refrigerator magnet.

The kind u use to magnet stuff closer to u
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
It depends on what kind of refrigerator you own.
You would need to define 'regular magnet' to get any kind of magnet.
a magnet Actually named magnetite, but it is a natural magnet.
