Magnetism — Flashcards

Answer

Magnetism is the property of an object by which it can attract small pieces of iron, nickel, cobalt, or steel. This attraction is due to the presence of magnetic poles and the magnetic field around th…

Answer

Natural magnets are naturally occurring minerals that possess magnetic properties. An example is magnetite or lodestone (Fe₃O₄), which attracts iron pieces.

Answer

A magnetic dipole consists of two equal and opposite magnetic poles (north and south) separated by a small distance. A bar magnet is a common example of a magnetic dipole.

Answer

When a magnet is freely suspended, it aligns itself approximately in the geographical north-south direction. The pole pointing toward geographic north is called the north pole of the magnet.

Answer

Magnets attract small pieces of magnetic materials like iron, nickel, and cobalt. The force of attraction is strongest near the poles of the magnet.

Answer

This occurs due to the interaction of magnetic fields. Field lines emerge from the north pole and enter the south pole. When two like poles face each other, their field lines oppose, causing repulsion…

Answer

Magnetic induction is the process by which a magnetic material becomes magnetized when brought near a magnet. The end closer to the magnet acquires opposite polarity, and the farther end acquires the …

Answer

The magnetic field is the region around a magnet where another magnet or magnetic material experiences a force. It is a vector quantity denoted by **B** and measured in Tesla (T).
