The physics of a solenoid and the electromagnet. The coils of a wire in a solenoid are arranged as shown below. . a. Draw the magnetic field line pattern for this arrangement of current. . b. A compass is placed below the solenoid as shown by the open circle below. How would the compass needle point? OO OO OO OOO 80 080 080 . c. Describe the location where the magnetic field strength of the solenoid is the strongest. . d. What could you add to the interior of the solenoid to create a stronger magnetic field? Explain, using the domain theory, why this is effective? . e. A second solenoid is placed to the right of the previous solenoid. The currents in the solenoid coils are arranged as shown below. 080509080 Would the coils attract or repel each other? Explain your reasoning
