Force between Two Parallel Currents: The force between two parallel currents can be described by Ampere’s law, which states that a magnetic field is produced around a current-carrying wire. When two parallel wires carry currents in the same direction, they produce magnetic fields that attract each other. When the currents flow in opposite directions, the magnetic fields repel each other.

Force between Two Parallel Currents Formula

The force between two parallel currents can be calculated using the following formula:

F = μ * I1 * I2 * d / (2 * π * r)

Where:

• F is the force between the two wires, in newtons
• μ is the magnetic permeability of free space (4π * 10^(-7) Tm/A)
• I1 and I2 are the currents in the two wires, in Amperes
• d is the distance between the wires, in meters
• r is the radius of the wires, in meters

It’s worth noting that the force between two parallel currents is proportional to the product of the currents, and inversely proportional to the square of the distance between the wires. This means that the force becomes weaker as the distance between the wires increases, and stronger as the currents increase.
