Question

Linus builds an electrical circuit with a battery and with wires that carry the current. As the battery weakens, the current also weakens.

How does this affect the magnetic field around the wires?

The field gets stronger.
The field gets weaker.
The field changes direction.
The field disappears completely.

Answer 1

As the battery weakens, the current flowing through the wires also decreases. The strength of the magnetic field generated around a wire is directly proportional to the amount of current that flows through it, according to Ampère's circuital law. Therefore, if the current weakens, the magnetic field around the wires will also weaken.

So, the correct answer is: **The field gets weaker.**
