What will happen to a compass needle when a compass is placed below a wire and a current is made to flow through the wire?

The compass needle will show deflection. This happens because when a current is passed through a conductor (here, wire) a magnetic field is produced around the conductor due to which the compass needle gets deflected.

Why does a compass needle move when placed near a wire carrying an electric current?

Why does a current-carrying wire cause a compass needle to move? The electric current creates a magnetic field that exerts a force on the compass needle and causes the compass needle to move.

How does the compass needle move when the compass is below the wire above the wire?

Electricity moved the compass needle which means electricity generates magnetic fields. So the magnetic field direction is different above and below the wire. This happens because there is actually a magnetic field created which goes around the wire. The compass needle continues to point magnetic north.

What happens when a compass is placed under a wire?

A: No matter where the compass is placed, when it is under the wire and the circuit is closed, the compass needle will point across, or perpendicular to, the wire.

How does a compass needle change direction when it is placed near a current carrying wire?

Magnetic field strength is inversely proportional to the distance from the wire. A compass needle is placed near a current – carrying straight wire . (2) Magnitude of electric current in the wire is increased . (3) Teh compass needle is displaced away from the straight wire .

In which direction will the compass needle point if it is held above the wire?

A compass needle placed above the wire points with its north pole toward the east.

What happens to a compass needle kept near by when current flows in a wire name the effect of electric current behind this phenomenon?

The needle of a compass is a tiny magnet, which points in the north-south direction. When an electric current passes through a wire, it behaves like a magnet. This magnetic effect of the electric current makes the compass needle deflect from the north-south direction.

When a magnetic compass is placed near a current carrying conductor compass?

When a current carrying wire is brought close to a magnetic compass then there will be a deflection in the magnetic compass due to the magnetic field formation. The magnetic field around a wire carrying electric current will form concentric circles around the wire.

When placed above a current carrying straight wire a compass needle points to the north but when placed below the same wire the needle points to the south?

Answer: When placed above a current carrying straight wire, a compass needle points to the north(which is the magnetic south pole), Hence magnetic field at point just above the wire is towards geometric south, so using Right hand thumb rule we find that current is towards east direction.

What happens to the needle of a compass?

The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet. In Experiment 1, when you bring the compass near a strong bar magnet, the needle of the compass points in the direction of the south pole of the bar magnet.

When a magnetic needle is placed near the current carrying conductor then deflection in magnetic needle?

A magnetic needle placed close to a current carrying conductor deflects due to the magnetic effect of the electric current. Because the magnetic needle (or its field) interacts with the magnetic field produced by the current carrying conductor it deflects.

When placed above a current carrying straight wire a compass needle points to the West but when placed below the same wire the needle points to the east?

If electrons flow towards west, the current equivalently move towards east. Hence from right hand thumb rule, the magnetic field above the wire is towards south, which is same direction as that of earth’s magnetic field.

Where is the needle on a compass placed?

A compass needle is placed above the wire points with its N-pole toward the east. In what direction is the current flowing? If a compass is put underneath the wire, in which direction will the needle point?

How do you use a compass correctly?

When you put your compass above the wire, the needle will align with the magnetic field pointing out of the page, Moving the compass to below the wire the needle will flip 180 degrees and now point into the page. I don’t want to begin the discussion of north and south poles, etc.

How is a compass affected by a magnetic field?

A compass will be most affected by the magnetic field of a current carrying wire when the plane of the compass is at 90 degrees to the wire, and lest effected when the plane of the compass is in the same plane as the wire. When a compass is placed on one side of the wire, it will point in one direction.

What happens if you put a compass above or below a wire?

Just know that the compass needle will turn 180 deg. Assume the wire is carrying current. compass will change the deflection due to current carrying wire in reverse direction if compass placed above or below the wire. 8 clever moves when you have $1,000 in the bank.
