6. The students decide to create an electromagnet based on their results from Experiments 1 and 2. Which two designs pair the electromagnet with expected results?

A An electromagnet with 10 loops attached to a 0.7 V power source will pick up about 30 pins.
B An electromagnet with 30 loops attached to a 3.0 V power source will pick up about 75 pins.
C An electromagnet with 40 loops attached to a 3.0 V power source will pick up only 15 pins.
D An electromagnet with 20 loops attached to a 0.7 V power source will pick up about 15 pins.
E An electromagnet with 30 loops attached to a 1.5 V power source will pick up only 25 pins.
