Laplace Law Experiment
Name: Aleksandra Zasadni Date:27/4-15
Research Question: What is the relationship between the current and the force exerted by the magnetic field in the wire?
Independent Variable: Current induced
Dependent Variable: Force exerted
Controlled Variables: Length of the wire, size of the magnet,
Materials Required/Used: power supply, stand, current balance, balance, magnets, 2 wires, a wire plate/conductor
Method: Place the magnets on the balance, and place a conductor connected to the current balance and placed on the stand. The current balance is
