Can non-metal materials cause deflections?
Day 3: Mapping a Dipole Magnetic Field Background Information Magnetism is a non-contact force. The magnet can affect materials across an intervening space. That is, we do not have to be at the location of the source object to detect it. The fact that the force acts across a space but can be modified (strengthened, weakened, redirected) by intervening materials creates an intellectual challenge. What is the important difference between materials which do not effect magnetic fields, those that enhance them, those that weaken fields, and those that redirect them? This may form an excellent question to place on the blackboard and leave for a few days to inspire investigation and thought. Students will investigate the shape of the magnetic field of a bar magnet. This will be done by placing the magnetometer at various locations and recording the direction of alignment of the sensor magnet. Students will look for the place where the magnetic field of the bar magnet can no longer be seen. Th
