This packet will serve as classwork and homework. Homework 1. What do the arrows in the drawing below tell you about the magnetic field? Magnetic field Force Magnet from the magnet's 2. Magnetic field lines always point north pole and its south pole. 3. When magnetic field lines are closer together, this means the force is at that location. a. weaker b. unchanged-the force is the same at all points in space. C. Stronger 4. Write the letter of the magnet next to the correct description of the net force that is exerted on it. Some descriptions may apply to more than one magnet. Magnetic field Source magnet attracting force Repelling force Twisting force. 5. In the diagram above, imagine that you flip magnet C so that its south pole is closer to the magnet. Now describe the net force felt by magnet C
