A student is planning an investigation to determine the relationship between magnetism and the movement of electrical charge in a circuit. A diagram of the circuit is shown.
The student is planning to make changes to the circuit to see how the changes will affect the number of paper clips that are picked up by the electromagnet. What is the likely effect of the magnetic field if the student adds more coils?
increase
decrease
no change
