Question

Based on the mage below, the ferromagnetic material is best described by which schematic A hard magnetic material has a(n) coercivity, H_c, compared to a soft magnetic material small large equivalent The reason a magnet can levitate above a superconductor is Superconductors are diamagnetic Superconductors are paramagnetic Superconductors are ferromagnetic Magnetic nanoparticles car be used in potential cancer fighting treatments by Hyperthermia therapy Triggered drug release Cellular reconstruction Both A & B Both B & C

Explanation / Answer

9) in absence of magnetic field the ferromagnetic substance has different domains in which electrons are aligned in each domain independant of other domains. In presence of magnetic field all domain electrons get aligned in a single direction.

Option C: is most suitable

10) Hard magnetic materials retain their magnetism. They are hard to get demagnetized as compared to soft magnets

so hard mangetic materials have high Coercivity and retentivity both.

11) The superconductor are perfect diamagnets

12) Hyperthermia is a technique of killing cancer tissues by exposing body tissue to high temperature. Nanoparticles are used for even distribution of heat in the cancer treatment

B) Triggered drug release : the drugs are delivered on the target site in the technique. The nanoparticles are used to encapsulate the drug.

Answer: A and B
