When the north pole of a bar magnet is brought near the sphere, the sphere is strongly attracted to the magnet. Which of the following is true if the magnet is reversed and its south pole is brought near the sphere? The sphere is unaffected by the magnet. The sphere is repelled by the magnet. The sphere is attracted to the magnet.Question 2 XXXXXXXX X X X X X X XXXX XXXXXXXX A particle travelling at 4.90 * 10" m/s enters a region of magnetic field with direction into the page as shown above.
