What else can I help you with?
Determine the direction in which a compass needle will point when held above a wire with positive charges moving west?
The compass needle will point towards the wire, perpendicular to the current flow. Since the positive charges are moving west, the magnetic field generated by their movement will induce a force on the compass needle causing it to point towards the wire.
Why does a compass needle placed near a current carrying wire show deflection?
A compass needle placed near a current-carrying wire shows deflection because the moving charges in the wire create a magnetic field around the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align with the direction of the current flow in the wire.
When a current flows from east to west what direction will a compass point to?
A compass needle aligns with the Earth's magnetic field, which typically points north. In this scenario, with a current flowing from east to west, the compass needle will still point north. The direction of current flow does not affect the orientation of the compass needle.
Why is a compass able to find an electric current?
A compass can detect an electric current because a moving electric charge produces a magnetic field around it. When an electric current flows through a wire, it creates a magnetic field that can be detected by the compass needle. This phenomenon is known as electromagnetism.
Describe what happens when you hold a compass close to a wire carrying a current?
When a compass is held close to a wire carrying a current, the magnetic field produced by the current will deflect the compass needle. This happens because a magnetic field is generated around the wire due to the flow of current, and the compass needle aligns itself with this magnetic field. The deflection of the compass needle can be used to determine the direction of the current in the wire.

True or False an electromagnet is created when electric current flows through a compass needle?
The real question should be how do you get current to flow through a compass needle.
An electric current cannot be used to deflect a compass needle?
An electric current can be used to deflect a compass needle. When an electric current flows through a conductor, it generates a magnetic field around it, which can interact with the magnetic field of the compass needle, causing it to deflect. This principle is the basis for electromagnetism.
What happens to the needle of a compass as a wire carrying electric current is placed across it?
The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
How would the compass respond when you turn on the current in this scenario?
The compass needle would align itself with the direction of the current flow.
Can an electric current be used to affect a compass needle?
Yes, an electric current can affect a compass needle because it creates a magnetic field. When the electric current flows through a wire, it generates a magnetic field around the wire, which can deflect the compass needle and change its direction.
How do you use a compass to find the flow through a wire?
A compass can be used to find the flow of current through a wire by placing the compass near the wire. The needle of the compass will align with the magnetic field created by the current flowing through the wire, indicating the direction of the current flow. The needle will point in the direction from which the current is coming.
What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
