How does a speaker make sound with electric energy?
A loudspeaker contains a metal coil, known as an electromagnet, that creates a magnetic field when an electrical current passes through it. It is the action of the electromagnet that is responsible for converting electrical energy into audible sound.
Electric current is produced when move through?
Electric current is produced when charged particles, such as electrons, move through a conductive material, creating a flow of electric charge. The movement of these charged particles generates an electric field, leading to the flow of current in a closed circuit.
What are materials that allow electric current to move through them?
Materials that allow electric current to move through them are called conductors. Common examples include metals such as copper, silver, and aluminum. Conductors have low resistance to the flow of electric current due to their ability to easily transfer electrons.
What and a conductor through which electric current travels through?
A conductor is a material through which electric current can easily flow. Metals like copper and aluminum are commonly used as conductors due to their high conductivity. When a voltage is applied across a conductor, electric charges move through the material, creating an electric current.
What 3 things do you need to have for electric current?
To have electric current, you need a source of electric potential difference (voltage), a closed circuit that allows the flow of charges, and a conductive material through which the electric charges can move.

When a magnetic field is used to create an electric current in a wire?
The magnetic field must be changing relative to the conductor (wire). So the wire could move through the field, or the field could move past the wire, or you could have a changing field (from an electromagnet with varying current).

If an electromagnet was free to move how would it move?
Electromagnet is the magnet which is becoming active so long current through the coil flows. If current stops then the magnetism disappears. If a core made up of soft iron is used then magnetism will become more intense but the magnetism exists so long the current flows. Any way electromagnet will behave just like a permanent bar magnet. So electromagnet would set itself along the earth's magnetic meridian.

What is the name of the particles which move when current flows through a solution?
Ions are the particles that move when current flows through a solution. They carry electric charge as they migrate towards the oppositely charged electrode.
Which type of materials allow the charges of an electric current to move freely through them?
Conductors, such as metals.
In solid Conductors Electric current is the flow of?
In solid conductors, electric current is the flow of electrons moving through the material. These electrons move in a coordinated manner in response to an applied electric field, creating the flow of current.
What happens to the compass needle when the circuit is shut off?
Yes it will show .It is because if electric current is passed through the wires then it will become an electromagnet and show magnetic properties.But there should be a circular coil in the circuit then only that part will show magnetic properties.
What is the flow of electrical charges called?
It is called an electric current.
