State two ways by which the magnetic field of a solenoid can be made stronger

Explanation

To strengthen the magnetic field of a solenoid, we can implement the following two methods:

### Step-by-Step Solution:

1. **Understanding the Solenoid**:
- A solenoid is a coil of insulated copper wire that generates a magnetic field when an electric current passes through it. The magnetic field behaves like that of a magnet.

2. **Increasing the Current**:
