Magnetism & Electromagnetism Tutorial

The video introduces magnetism, explaining how magnets interact with metals like iron, nickel, and cobalt. It covers magnetic poles, fields, and how compasses align with Earth's magnetic field. The relationship between electricity and magnetism is explored, highlighting electromagnets. Practical applications and resources for further learning are provided.

What happens when two North poles of magnets are brought close together?

• They have no effect on each other

• They attract each other

• They repel each other

• They create a spark

In which direction do magnetic field lines point?

• From South Pole to North Pole

• In a circular motion

• From North Pole to South Pole

• Randomly

What is the primary function of a compass?

• To amplify sound

• To measure temperature

• To detect magnetic fields

• To calculate distance

What is an electromagnet?

• A magnet that cannot be turned off

• A permanent magnet

• A natural magnet

• A magnet powered by electricity

How can you increase the strength of an electromagnet?
