What is the value of magnetic field near the end of a current carrying solenoid?

Explanation

To find the value of the magnetic field near the end of a current-carrying solenoid, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Solenoid Configuration**:
A solenoid is a long coil of wire that generates a magnetic field when an electric current passes through it. The magnetic field inside a solenoid is uniform, but it varies near the ends.

2. **Identify the Relevant Formula**:
