What is the approximate ratio of the number of paper clips picked up by the 50-coilelectromagnet?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.

Calculate the slope of the 25-coil line and the 50-coil line to determine the average number ofpaper clips that a 1 V battery would pick up.
Solution
a. The ratio of the number of turns of the 50-turn electromagnet to the number of turns of the 25-coil electromagnet is 2:1. This is because 50 turns is twice as many as 25 turns.
b. The approximate ratio of the number of paper clips picked up by the 50-coil electromagnet to the 25-coil electromagnet is 13:6.
-
Doubling the number of coils generally doubles the strength of the electromagnet. This is because the magnetic field strength of an electromagnet is directly proportional to the number of turns in the coil.
-
Doubling the voltage also generally doubles the strength of the electromagnet. This is because the magnetic field strength of an electromagnet is directly proportional to the current flowing through the coil, and the current is directly proportional to the voltage (according to Ohm's law).

Without the graph, it's impossible to predict how many paper clips a 7.5 V battery would pick up for both the 25-coil electromagnet and the 50-coil electromagnet.
