Ensure the ultimate safety of your horses, cattle, sheep, livestock, dogs, and other pets with high tensile fence or other electric fencing. Our farm fencing accessories and electric horse fence supplies are also ideal for deterring predators, deer, and other garden pests. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Field Structures . and Magnetic .

The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in.
