Magnetism Concepts and Properties

The video introduces magnets and magnetism, explaining how magnets create a magnetic field that attracts magnetic objects. It differentiates between magnetic and non-magnetic objects, highlighting materials like iron, nickel, and cobalt. The video describes the poles of a magnet and demonstrates an experiment showing how like poles repel and unlike poles attract. It also explains that cutting a magnet results in two new magnets, each with its own poles. Finally, it discusses Earth's magnetic properties due to its iron and nickel core, and mentions that strong magnets can attract objects even underwater.

What is the area around a magnet where magnetic force is exerted called?

• Magnetic Circle

• Magnetic Area

• Magnetic Field

• Magnetic Zone

Which of the following is NOT a magnetic object?

• Cobalt rod

• Wooden block

• Nickel coin

• Iron nail

Which of the following metals is NOT typically attracted to a magnet?

• Iron

• Nickel

• Cobalt

• Copper

What happens when a magnet is freely suspended in air?

• It points East-West

• It points North-South

• It spins continuously

• It remains stationary

What is the term for the end of a magnet that points towards the North?

• Equator Pole

• North Pole

• Magnetic Pole

• South Pole

What occurs when like poles of two magnets are brought close to each other?

• They neutralize each other

• They repel each other

• They attract each other

• They stick together

What is the result of cutting a magnet into two pieces?

• It loses its magnetic properties

• It creates two new magnets

• It only has one pole

• It becomes non-magnetic

Why does Earth behave like a magnet?

• Because of its gravitational field

• Due to its rotation

• Because of its iron and nickel core

• Due to its atmosphere

What can a strong magnetic field do even under water?

• Repel water

• Attract non-magnetic objects

• Pull magnetic objects

• Create waves
