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.


Why does a compass change direction when it is near a current-carrying wire?

A compass needle is deflected when placed near a current-carrying wire due to the magnetic field generated by the flow of electric current. The magnetic field produced by the current interacts with the Earth's magnetic field, causing the needle to align in a different direction.


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.


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.


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.

What do you mean by magnetic affect of electric?

The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

What happens when a compass is palced near a current carrying conductor?

When a compass is placed near a current-carrying conductor, the magnetic field produced by the current can interact with the compass needle, causing it to deflect from its original position. This phenomenon is known as the magnetic field produced by the current affecting the magnetic needle in the compass. The direction of the deflection will depend on the orientation of the current and the compass in relation to each other.


Why does a current carrying wire deflect a magnetic compass?

A current-carrying wire generates a magnetic field around it due to the flow of electric charges. When the wire is placed near a magnetic compass, the magnetic field produced by the wire interacts with the magnetic field of the compass needle, causing the needle to deflect and align with the direction of the wire's magnetic field.


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.


What happens if the compass is placed under the wire?

Placing a compass under a current-carrying wire can cause the needle to deflect due to the magnetic field produced by the electric current. This phenomenon, known as the right-hand rule, demonstrates the relationship between electric current and magnetic fields.


Who discovered magnetic field of electric current?

Hans Christian Oersted discovered the magnetic field of electric current in 1820. He observed that a compass needle was deflected when placed near a wire carrying an electric current, showing a relationship between electricity and magnetism.
