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 a electric current be used to deflect a compass needle?
Yes, an electric current can generate a magnetic field that can deflect a compass needle. This phenomenon is known as electromagnetism and is the basis for how devices such as electromagnets and speakers work.
Can an electric current be used to deflect a compass needle?
Yes, an electric current can create a magnetic field that can deflect a compass needle. This phenomenon is known as the Oersted Effect and demonstrates the relationship between electricity and magnetism.
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.
Can tap water deflect compass needle?
Yes because tap water is a good conductor of electricity.
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.
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.
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 kind of test can determine that an electric current is flowing in a straight copper wire is connected to a battery?
A compass needle test will determine whether a current is flowing in the wire.IF the current is flowing the compass needle will deflect from alignment with the wire.
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.
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.
Why does a compass needle deflect in a magnetic field?
A compass needle is lightly magnetized, and will align itself with the lines of magnetic force at your locale. *It will not necessarily point to the Poles. The South magnetic pole is currently at about 68 deg S - some long way from 90 deg.
