Lenz Law 

• Lenz Law apparatus is a simple and effective way to demonstrate induction & Lenz Law of 
        electrodynamics.
• The metal hoops (one open and one closed) are freely moving on a centrally mounted pin.
• In the product photo above, you have a complete closed circuit (loop) on the right.
• When a magnetic field is introduced (from a bar magnet being moved toward the closed loop), 
        we have an electrical current and a magnetic field that will repel against the original magnetic 
        field.
• This is demonstrated when the closed loop moves away from an approaching bar magnet.
• This is Lenz law.
• Alternately, when you approach the open circuit (open loop) on the left with a bar magnet, 
        nothing will happen.
