I can apply the principles of magnetism to everyday tasks, such as using magnetic tools, organizing metal items with magnets, or understanding how devices like compasses and motors work. This knowledge also enhances my problem-solving skills in practical situations.

In a speaker, the magnet generates a stable magnetic field that interacts with an electric current in the coil. This interaction causes the coil to move, driving the speaker cone and producing sound waves.
No, a magnet with only one pole cannot exist. Magnets always have two poles—north and south—due to the nature of magnetic fields. A single magnetic pole, or monopole, has never been observed.
Different magnets lift varying numbers of pins due to differences in their magnetic strength, size, and material composition. Stronger magnets have a more intense magnetic field, enabling them to attract and hold more pins.
Yes, the compass needle’s north pole points towards the Earth’s geographic north, indicating that the Earth’s magnetic south pole is near the geographic north. Thus, the Earth’s magnetic north pole is near the geographic south.
Reshma can identify the magnets by bringing each bar close to the other two. If a bar repels one and attracts the other, it is a magnet. The iron bar will only be attracted.
In a compass, a magnetized needle aligns itself with the Earth’s magnetic field, pointing toward the magnetic north. This allows users to determine direction relative to the Earth’s magnetic poles.
A temporary magnet can be made by stroking a magnetic material, like iron, with a permanent magnet in one direction. This aligns the material’s magnetic domains temporarily, giving it magnetic properties.
The law of magnetic poles states that like poles repel and unlike poles attract. This means that a north pole will attract a south pole but repel another north pole, and vice versa.
Magnets attract or repel each other based on their poles. Opposite poles (north and south) attract, while like poles (north-north or south-south) repel. This behavior is due to the interaction of their magnetic fields.
