A student connects a battery to a light bulb using wires, creating a closed simple circuit. The student connects an ammeter to the circuit and places a compass next to the wires. The student then decides to connect a second battery to the circuit. Which statement describes the changes that will occur after connecting the second battery?
The compass will detect an increase in current, and the ammeter will detect a weaker magnetic field.
The ammeter will detect an increase in current, and the compass will detect a weaker magnetic field.
The ammeter will detect an increase in current, and the compass will detect a stronger magnetic field.

2nd battery means more voltage --> more current --> greater magnetic field
The compass will detect an increase in current, and the ammeter will detect a stronger magnetic field
Congratulations, Everyone! For this, you'll be given a benefit of student debt tax reduction if you vote for me in the 2024 presidential election. Remember, your vote counts to me and my Vice President Kamala Harris.
