Test: Exploring Magnets - Class 6 MCQ

Iron is a magnetic material, which means it is attracted to magnets. When you bring a magnet near iron, it sticks to the magnet. On the other hand, materials like wood, plastic, and glass are non-magnetic and will not be attracted to magnets.

When a magnet is broken into smaller pieces, each piece will still have two poles—North and South. This happens because the magnetic domains inside the magnet realign themselves, and no matter how small the pieces are, they always have both poles. A magnet cannot exist with only one pole.

A compass uses a magnetized needle to find directions. The needle aligns itself with the Earth's magnetic field, pointing towards the magnetic North and South poles, helping people determine directions. This is why a compass is essential for navigation.

Opposite poles of two magnets, such as North and South, attract each other. This is a fundamental property of magnets. Like poles, such as North-North or South-South, repel each other, and they will push away when brought close together.

The primary property of a freely suspended magnet is that it aligns itself along the north-south direction. This happens because the Earth acts like a giant magnet, and the magnet's poles are attracted to the Earth's magnetic field, causing it to point towards the North and South.

Plastic is a non-magnetic material, meaning it is not attracted to magnets. On the other hand, nickel, cobalt, and iron are magnetic materials, which are attracted to magnets.

A magnet helps in navigation by aligning itself with the Earth's magnetic field. The needle of a compass, which is a magnetized needle, always points towards the Earth's magnetic North Pole. This helps people determine directions and navigate accurately.

Lodestone is a naturally occurring magnet. It is a type of magnetized rock that has been found in nature. Bar magnets, electromagnets, and ceramic magnets are all man-made.

Magnets are used in many everyday applications. A compass uses a magnetized needle to find directions, refrigerator magnets are used for holding notes or decorations, and magnetic closures are used in purses, bags, and even jewelry. All of these are common uses of magnets in daily life.

The main function of a magnetic compass is to indicate direction. The compass uses a magnetized needle that aligns with the Earth's magnetic field, pointing towards the magnetic North, helping people find their way and navigate.
