What is a solenoid? Draw the pattern of magnetic field lines of (i) a current carrying
solenoid and (ii) a bor magnet. List two distinguishing features between the two fields.

Explanation

### Step-by-Step Solution

**Step 1: Define a Solenoid**
A solenoid is defined as a closely wound cylindrical coil of wire that acts as a magnet when an electric current passes through it.

**Step 2: Draw the Magnetic Field Lines of a Current-Carrying Solenoid**
To visualize the magnetic field lines of a current-carrying solenoid:
- Draw a cylinder to represent the solenoid.
