PPT-Electric Fields

Electric fields are created by electric charges Any object with a charge has an electric field around it Opposite charges attract each other like charges repel An electric field is a region in which a charge experiences a force . 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. We offer the widest selection of horse fencing, electric fences, polytapes, energizers, polyrope, fencing accessories and other equine products.
