Lab: Magnetic and Electric Fields

Question 1

Predict what would happen to the strength of the electromagnet in each situation.

Revolt · Accepted Answer

Using a battery with a higher voltage:: stronger force of attraction; Wrapping the wire around the nail only three times:: weaker force of attraction; Changing the direction of the current by reversing the battery connections:: no change; Using a plastic stick in place of the iron nail:: weaker force of attraction; Holding the nail vertically rather than horizontally:: no change
