When the magnet is suspended freely, its north and south poles are always pointed towards?

Explanation
When a magnet is suspended freely , its north pole will point towards the Earth's magnetic South pole (which is located near the Earth's geographic North pole), and its south pole will point towards the Earth's magnetic North pole (which is located near the Earth's geographic South pole). This is because opposite poles attract, and the Earth's magnetic field is strong enough to align the magnet's poles.

Explanation
Iron is a ferromagnetic material, which means it is strongly attracted to magnets . Therefore, an iron kettle will be attracted to a magnet .

Explanation
Wood is an insulator and cannot conduct electricity. So it cannot be used to complete a circuit.

Explanation
An open circuit provides an incomplete path for the current to flow through. As the circuit is broken or disconnected , preventing electricity from flowing.

Explanation
A closed circuit provides a complete path for the current to flow through. It allowing electricity to flow from the power source , through the wire, and back to the power source.

Explanation
An open circuit is an electrical circuit that is broken or disconnected, and electricity cannot flow. When the wire is disconnected, the circuit is open, and the bulb is off.

Explanation
A close circuit, also known as a closed circuit. It is an electrical circuit that is complete and allows electricity to flow from the power source, through the wire, and to the bulb , causing it to light up.

Explanation
Insulators are materials that resist the flow of electricity, such as rubber, glass, wood, and plastic. They have a high resistance to electric current and are used to prevent the flow of electricity.

Explanation
A thermal conductor is a material that allows heat energy to flow through it easily. Such as metals like copper, aluminum, and iron.

Explanation
Conductors are materials that allow electricity to flow through them, such as copper, aluminum, and gold. They have a high concentration of free electrons, which are able to move freely within the material , carrying electrical charge with them. Materials that do not allow electricity to pass through them are called insulators .
