Understanding the World's Strongest Magnet

The video explores the world's strongest magnet, which generates a magnetic field of 45 Tesla, nearly a million times stronger than Earth's. It demonstrates experiments with a Nerf football containing steel washers and the use of ferrofluid, which aligns in an external magnetic field, forming ridges even meters away from the magnet.

How much stronger is the magnetic field of the world's strongest magnet compared to Earth's magnetic field?

• 1 million times stronger

• 100 million times stronger

• 10,000 times stronger

• 100 times stronger

What was placed inside the Nerf football to demonstrate the magnet's effect?

• Wooden chips

• Steel washers

• Plastic beads

• Rubber bands

What is ferrofluid primarily composed of?

• Nanoscale pieces of magnetite

• Microscale pieces of iron

• Nanoscale pieces of copper

• Microscale pieces of aluminum

What happens to ferrofluid when exposed to a strong magnetic field?

• It solidifies

• It changes color

• It forms parallel ridges

• It evaporates

How far can the effects of the magnet be observed on the ferrofluid?

• Only within a meter

• Even meters away

• A few centimeters away

• Only at the surface
