What Lies Beyond: Exploring the Magnitude of Magnetic Fields
What is the formula for calculating the magnetic field created by a current-carrying wire at a given distance?
The magnitude of the magnetic field at point P, located 0.042 meters away from the current-carrying wire, can be calculated using the formula for the magnetic field created by a straight wire carrying current.
The Formula for Calculating the Magnetic Field
The magnetic field generated by a current-carrying wire is given by the formula B = (μ₀ * I) / (2π * r), where:
- B represents the magnetic field
- μ₀ is the permeability of free space (4π × 10^(-7) T·m/A)
- I is the current
- r is the distance from the wire
By plugging in the values of the current (1.20 A) and the distance (0.042 meters) into the formula, we can calculate the magnitude of the magnetic field at point P.
Exploring the world of magnetic fields can be an intriguing journey. Understanding how these invisible forces interact with each other and the world around us can lead to remarkable discoveries.
