← ScienceWhich consequence results when ferromagnetic nanoparticles clump in ferrofluid?
A)Decreased magnetorheological effect observed✓
B)Curie temperature greatly increases
C)Enhanced superparamagnetic susceptibility results
D)Increased carrier fluid viscosity develops
💡 Explanation
The magnetorheological effect decreases because aggregation limits the nanoparticles' individual alignment under an external field, because it encourages "dipolar interactions". Therefore, the suspension's ability to change viscosity diminishes, rather than enhancing the other three alternative effects
