8. Students make predictions about the magnetic field of the new electromagnet in Experiment 4. Which prediction correctly states how replacing the core will change the magnetic field in the new electromagnet compared to the original?
A The size of the magnetic field will increase, causing the voltage running through the wire to
decrease.
B The size of the magnetic field will decrease, causing the new electromagnet to pick up fewer
pins.
C The strength of the magnetic field will decrease, causing the voltage running through the wire
to increase.
D The strength of the magnetic field will increase, causing the new electromagnet to pick up
more pins.
