Question

A student builds an electromagnet using a variable power source and 40 turns of wire. The electromagnet is used to pick up metal paper clips. The student changes the voltage and counts the number of paper clips that are picked up. Which table could be the data the student collected?

Answer 1

I don’t see the four tables in your message. Could you either paste the data from Tables A–D (or upload an image) so I can compare them, or tell me which table shows which numbers?

Tip to choose the correct table yourself: with the number of turns fixed, the magnet’s field strength is proportional to the current, and for the same coil resistance current is roughly proportional to voltage. So the correct table should show the number of paper clips picked up increasing as the voltage increases (a reasonably steady upward trend, not random or decreasing).
