1) Analyze the student data as if you were Ms. Olivera. One group clearly
won the challenge. What aspects of the winning design accounted for
the strength of Group #2's electromagnet?
A)
Using a 9-volt battery for more electrical energy.
Longer wire allows for more turns around the iron
core
More turns of wire around the core and the maximum
voltage
Using a double-nail core and more turns of wire
around that core.
