1. What is the direction of the magnetic field at point A? 2. The magnet shown below is cut in half. Show what happens to the two pieces by drawing the poles on cach piece. 3. At which point is the magnetic field strength the greatest in the diagram below? 4. A compass is placed at point A in the diagram below. In which direction will it point (make sure you label the north and south poles of the compass)? 5. Why can't magnetic field lines ever cross? 6. Explain by use of a diagram how an un-magnetized piece of iron becomes magnetized when held near a bar magnet.
