Question

1. Show the temperature effect on magnetic properties of (a) ferrites, (b) ferromagnetic materials
2. Are there specific health risks from nano products?

Answer 1

Answer:

(a) ferrites,

Explanation:

step by step explanation

Answer 2

Answer:

answer 1- As the temperature of the ferromagnetic material is raised, the thermal energy of the atoms increases. At very high temperature, the thermal energy is sufficient to break the domains and ferromagnetic materials become paramagnetic.

answer 2- Out of three human studies, only one showed a passage of inhaled nanoparticles into the bloodstream. Materials which by themselves are not very harmful could be toxic if they are inhaled in the form of nanoparticles. The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems.
