Look at the data table and graph for the 50-coil electromagnet. with the 1.5 v battery, the electromagnet picked up an average of 13 paper clips, while the 25-coil electromagnet picked up an average of 6 paper clips. a. what is the ratio of the number of turns of the 50-turn electromagnet to the number of turns of the 25-coil electromagnet? b. what is the approximate ratio of the number of paper clips picked up by the 50-coil electromagnet? 3. what does doubling the number of coils do to the strength of the +electromagnet? 4. what does doubling the voltage do to the strength of the electromagnet? 5. using the graph, predict how many paper clips a 7.5 v battery would pick up for both the 25coil electromagnet and the 50-coil electromagnet. 6. calculate the slope of the 25-coil line and the 50-coil line to determine the average number of paper clips that a 1 v battery would pick u
