When an electric current flows through a wire, it creates a magnetic field around the wire. If this wire is placed in the presence of another magnetic field, the two fields can interact, causing the wire to deflect. This phenomenon is known as the magnetic deflection of an electric current.

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.
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 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.
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.
Can an electric current be used to deflect a compass needle?

How did Oersted discover the relationship between an electricity and magnetism?
Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.
How do you show that electric current causes magnetism?
Put a wire carrying an electric current near a compass and it causes the needle to deflect.

What does a galvonometer measure?
A galvanometer measures electric current by detecting the presence and strength of the current flowing through it. It typically consists of a coil of wire within a magnetic field, which causes the coil to deflect in proportion to the current passing through it.
How do you communicate using electricity and magnetism?
Communication takes on many forms. It can be by a system of flashing lights, a movement of an indicator, or by reproducing sound.A signal light can be made using an electric lamp, an electrical source and a switch.The wire separating the lamp and the switch can be many miles and still work.In the same way, the electric current can be made to power a solenoid (electromagnet) and deflect a needle.Using fine control of an electric current, sound can be modulated onto a voltage and reproduced at the other end using a coil and diaphragm, a telephone.Electricity and magnetism form the basis of electromagnetic waves, known as radio waves. There are many different ways of modulating the signal onto a carrier wave and many different frequencies that can be selected and separated.The digital world is controlled by electricity being either 'on' or 'off', just two states, which can be manipulated very rapidly to form a code, containing masses of information.Digital information can be sent using electricity (copper cables), or light (fiber optic), or radio. DAB, DTV, WLAN, Bluetooth, etc.

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.
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.
Is electric field can deflect y-rays?
As gamma rays are neutral it cannot be deflected by electric field.
