Questions and Answers

What happens to the distance between a magnet and an attracted object when the magnet is submerged in water?

It slightly decreases due to water's density (correct)
It slightly increases due to water's diamagnetic properties
It remains the same as in air
It increases significantly

What effect does buoyancy and water pressure have on the attraction strength of a magnet underwater compared to in air?

Completely eliminates the attraction strength
No impact on the attraction strength
Slightly reduces the attraction strength (correct)
Increases the attraction strength

How does the magnetic field surrounding a magnet behave when submerged underwater?

Expands significantly beyond normal limits
Collapses and disappears
Becomes weaker and ineffective
Extends underwater and influences other ferromagnetic materials (correct)

What is the effect of water's diamagnetic properties on the relationship between a magnet and ferromagnetic objects underwater?
