$(i)$. Artificial magnets are made in different shapes such as bar $\underline{magnet,\ horse\ shoe}$ and $\underline{cylindrical}$.

Explanation:
Artificial magnets are made in three most common shapes such as cylindrical, horseshoe, and bar as shown in the figure below.
.


$(ii)$. The Materials which are attracted towards a magnet are called $\underline{magnetic}$.
Explanation:
Materials that are attracted by magnets are called magnetic materials. 
Examples of magnetic materials
Metals like iron, nickel, and cobalt are magnetic materials.

$(iii)$. Paper is not a $\underline{magnetic}$ material.

Explanation:
Paper is not attracted to magnets, so paper is a non-magnetic material. Materials that are not attracted by magnets are called non-magnetic materials. 
Examples of non-magnetic materials:
Plastic, rubber, glass, wood, and paper are examples of non-magnetic materials.

$(iv)$. In the olden days, sailors used to find direction by suspending a piece of $\underline{magnet}$.

Explanation:

A magnet can be used to navigate the location due to its directive property. A a freely suspended magnet always pointing in a north-south direction. Compass is a good example of this property. 


$(v)$. A magnet always has $\underline{two\ poles}$.

Explanation:

Every magnet has two poles-

1. North Pole$(N)$

2. the South Pole$(S)$

Here N denotes the North Pole of the magnet and S denotes the South Pole of the magnet.
