Question

You and your classmates are experimenting with things that can affect the strength of an electromagnet. For this trial, you tested the strength of the electromagnet with 25 coils of wire at different voltages. The data table includes the number of paperclips picked up in each trial. If you were to increase the coils of wire to 50 turns, what would you expect to happen to the strength of the magnet at each of the voltages? Estimate the average number of paperclips that can be picked up for each voltage using 50 turns of wire.

Answer 1

Answer:

A) The greater the voltage, the stronger the electromagnet.

Explanation:

While the number of coils does also affect the strength of the electromagnet, this cannot be inferred from the data provided. An electromagnet with a 3V battery has 40% the strength of one with a 6V battery. There is no data provided for the 4.5 V battery.

Answer 2

Answer: A) 1.5V=11.2; 3V=16; 4.5V=29.5; 6V=44
