1. The strength of an electromagnet depends on several factors, including the number of coils wrapped around the core of the electromagnet and the voltage of the power source. The greater the number of coils, the stronger the electromagnet. And, the greater the voltage, the stronger the electromagnet.

Make a line graph of the data shown in the photo given. On the same graph, show the average number of paperclips each electromagnet picked up for each voltage tested. Plot the voltage on the x-axis and the average number of paper clips picked up on the y-axis. Scale the x-axis in intervals of 1.5 volts and scale the y-axis in intervals of 5 paperclips. please provide visual.

2. Look at the data table and graph for the 25-coil electromagnet. With 1.5 V battery, the electromagnet picked up an average of 6 paper clips, and with 6.0 V battery, it picked up an average of 23 paper clips.

a. How many times stronger than the 1.5 V battery is the 6.0 V battery?

b. What is the approximate ratio of the number of paper clips picked up using the 6.0 V battery to the number picked up using the 1.5 V battery?

c. Is this a direct relationship or an indirect relationship?

2. Look at the data table and graph for the 50-coil electromagnet. With the 1.5V battery, the electromagnet picked up 13 paper clips, which the 25 could electromagnet picked up an average of 6 paper clips.

a. What is the ratio of the number of turns 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 25-coil 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 thats a 1V battery would pick up.
