2) In the previous problem, we discussed the magnetic field lines associated with a bar magnet. In the following, we instead focus on magnetic field vectors, noting that: Field vectors indicate the magnitude and direction of the field at that point in space . Field vectors at each point in space are tangent to any field line through that point Two identical bar magnets are arranged as shown below. Sketch the approximate magnetic field vectors (not field lines) at the four, labeled points for: a) Just the horizontal top magnet S N C . D. N A . S b) When both are present S N C . B N A . S Explain how you determined the field vectors for the case when both magnets are present
