Read about Manny's investigation then answer the questions.
1. What is a benefit of Manny's electromagnet?
2. What are two things Manny could do to increase the strength of the electromagnetic force?
; 3. Look at the picture closely. What evidence is there that the electromagnet exerts a force on the
paper clips, even though they are not touching?
4. Many detaches the two wires from the battery and reattaches them to the opposite terminals.
Explain how this changes the current and magnetic field.
5. Suppose you pull the paperclips away from the nail. Explain how the potential energy between
the paperclips and the nail changes.

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
