The magnitude of magnetic field at a point due to a current carrying small element of a conductor does not depend upon

Options

A. currnt in the element
B. diameter of the element
C. length of the element
D. distance of the point from the element

Explanation

To solve the question regarding the factors on which the magnitude of the magnetic field at a point due to a current-carrying small element of a conductor does not depend, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Formula**: The magnetic field \( dB \) at a point due to a small current-carrying element \( dl \) is given by the formula:
\[ dB = \frac{\mu_0}{4\pi} \cdot \frac{I \, dl \, \sin \theta}{r^2} \]
