Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact. MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. HS-PS2-5. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. Safety: Be sure to stress being careful with the items used in the lab, so as not to break them. Be careful not to pinch fingers between the neodymium magnets.
