What else can I help you with?
Explain the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, the flow of current generates a magnetic field around the wire, which can influence the direction of the compass needle. The compass needle will align itself with the magnetic field produced by the current flowing through the circuit, causing it to deflect from its original position.
What instrument measures the direction of current?
A compass can be used to measure the direction of current flow in a circuit by aligning the compass needle with the magnetic field created by the current.
What is the name of the force that changes direction of a compass needle?
The force that changes the direction of a compass needle is called the magnetic force, which is generated by the Earth's magnetic field.
Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
What direction does the magnetic needle of a compass point to?
The magnetic needle of a compass points towards the Earth's magnetic North Pole.

What direction is a red needle attracted to in a compass?
north
What is the circuit's total resistance?
You take the wire(s) that are in the circuit and place it on on a compass. Hold the compass still and the needle in the compass will move. However far that the needle is turned will detrmine how much resistance is in the circuit. (You know you have done this correctly if the needle in the compass spins counter clockwise.) Hope this helps you out :)
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.
What direction does the needle of a magnetic compass point?
The needle of a magnetic compass points towards the Earth's magnetic north pole. This allows users to determine their direction relative to the magnetic poles.
What is the moveable bar in a compass called?
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.
A compass needle changes direction if the flow of electricity in the wire near it is reversed?
Yes, when the flow of electricity in a wire near a compass needle is reversed, the magnetic field generated by the current also changes direction. This change in magnetic field influences the orientation of the compass needle, causing it to change direction accordingly.
How compass changes direction?
A compass needle aligns itself with the Earth's magnetic field, pointing towards the magnetic North Pole. When the compass is moved or rotated, the needle remains aligned with the magnetic field, causing it to change direction accordingly.
