SUMMARY
When a conductor is charged with current electricity, it generates a magnetic field, a phenomenon known as electromagnetic induction. The strength of this magnetic field is directly proportional to the current flowing through the conductor and can be calculated using the Biot-Savart law. The formula B = (μ0 * I) / (2π * r) defines the magnetic field strength, where B is the magnetic field strength, μ0 is the permeability of free space, I is the current, and r is the distance from the conductor. The direction of the magnetic field is determined by the direction of the current flow.
