Figure 1.9: Force between two long straight parallel wires.
2. Relevant equations: F = [(permittivity constant)(current 1)(current 2)(length)] / (2pi)(distance apart) This is the equation for the magnetic force between two wires. 3. The attempt at a solution.
Experiment 8: Magnetic Forces. OBJECTIVES. 1. To investigate the magnetic force between two current carrying wires. 2. To measure the permeability constant µ0 . INTRODUCTION.
...current-carrying wires and measure the fundamental constant μ0, the permeability in free space.
Problems in General Physics → Electrodynamics → Constant Electric Field in Vacuum. 3.1. Calculate the ratio of the electrostatic to gravitational interaction forces between two electrons, between two protons.
1. Force between current-carrying wires Wire 1 has a length L (where L is "long") and carries a current I0.
The force felt between two parallel conductive wires is used to define the ampere—the standard unit of current.
To investigate the magnetic force between two parallel current-carrying wires and determine the magnetic permeability of free space, µo.
In magnetostatics, the force of attraction or repulsion between two current-carrying wires (see first figure below) is often called Ampère's force law. The physical origin of this force is that each wire generates a magnetic field, as defined by the Biot–Savart law...
In the early 1800’s several researchers noted that there is a force between two parallel wires that carry a steady current .
