WILL GIVE BRAINLIST JUST PLZ HURRY!!! 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.

Answer:

1.The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.
