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.

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.

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.

Even after breaking, each piece becomes a new magnet with both poles. It’s impossible to isolate a single pole.

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 lose their strength if heated, hammered, or dropped. Proper storage with opposite poles and soft iron keeps them safe.

Iron filings show the magnetic field only when a magnet is nearby. Since plastic is non-magnetic, no pattern appears around it.

Like poles (north-north or south-south) repel. Since the cars moved apart, their facing poles must be the same.
