Formula Used in “Magnetic Field of a Straight Current-Carrying Wire Calculator”
The magnetic field ((B)) produced by a straight, long current-carrying wire is calculated using the following formula:
B = frac{{mu_0 cdot I}}{{2 cdot pi cdot r}}
Where:
Step-by-Step Breakdown of the Formula
- B: Represents the magnetic field strength at a distance r from the wire, measured in Tesla (T).
- (mu_0): This is the permeability of free space, a constant defined as approximately 4pi times 10^{-7} , T cdot m/A.
- I: The electric current flowing through the wire, measured in Amperes (A).
- r: The distance from the center of the wire to the point where the magnetic field is being calculated, measured in meters (m).
Example Calculation
To better understand how to apply the formula, let’s go through a real-world example.
Example Scenario
Suppose we have a straight wire carrying a current of I = 5 A, and we want to find the magnetic field at a distance r = 0.1 m from the wire.
Input and Output Table
| Parameter | Value |
|---|---|
| Current (I) | 5 A |
| Distance (r) | 0.1 m |
| Permeability of free space ((mu_0)) | 4π × 10-7 T·m/A |
Calculation Steps
- Substitute the values into the formula:
B = frac{{4pi times 10^{-7} , T cdot m/A cdot 5 , A}}{{2 cdot pi cdot 0.1 , m}}
- Simplify the expression:
B = frac{{20pi times 10^{-7}}}{{2pi cdot 0.1}} = frac{{20 times 10^{-7}}}{{0.2}} = 1 times 10^{-6} , T
