In summary: So, selecting A) leave the magnet alone is the correct answer. In summary, when a current flows through a wire loop, it creates a magnetic field that can attract or repel a nearby bar magnet. However, if there is no current, there will be no interaction with the magnet.

## Homework Statement

A loop of wire is connected to the terminals of a battery.
See Diagram: http://www.webassign.net/walker/22-35.gif

The A terminal is of higher voltage, so the current travels clockwise from A to B through the loop.

If you have the ability to send whatever current you like (or none at all) into this wire loop, how can you affect the nearby bar magnet?
(Select all that apply.)
a) leave the magnet alone
b) repel the magnet
c) attract the magnet

## Homework Equations

n/a -- conceptual question.

## The Attempt at a Solution

so, my thought is that you a current through the loop if you EITHER attract or repel the magnet and move it through the loop. If you leave it alone, there will be no current.

I've tried selecting B) and C) but that's wrong.
Are choices A) B) and C) all correct?

No, choices B) and C) are not all correct. The correct answer is A) leave the magnet alone. When a current flows through a wire, it creates a magnetic field around the wire. This magnetic field will interact with the magnetic field of the bar magnet, causing the magnet to either be attracted or repelled depending on the direction of the current. However, if there is no current flowing through the wire, there will be no magnetic field and therefore no interaction with the magnet.

## What is a loop of wire connected to the terminals of a battery?

A loop of wire connected to the terminals of a battery is a simple circuit that allows electric current to flow from one end of the battery to the other, creating a complete circuit.

## How does a loop of wire connected to a battery work?

When a loop of wire is connected to the terminals of a battery, the battery creates a potential difference or voltage between the two ends of the loop. This voltage causes electrons to flow through the wire, creating an electric current.

## What are the benefits of using a loop of wire connected to a battery?

A loop of wire connected to a battery is a simple and efficient way to create an electric circuit. It can be used to power various devices and is a fundamental component of many electrical systems.

## Can a loop of wire connected to a battery be used in different ways?

Yes, a loop of wire connected to a battery can be used in various ways. It can be connected to other components, such as resistors or light bulbs, to create more complex circuits. It can also be used to charge batteries or power electronic devices.

## Are there any safety concerns when working with a loop of wire connected to a battery?

Yes, there are a few safety concerns to keep in mind when working with a loop of wire connected to a battery. Make sure the battery is the correct voltage and type for your circuit, and always handle it carefully to avoid short circuits or electric shocks. It is also important to disconnect the battery when not in use to prevent overheating or damage to the circuit.
