Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Maximum magnetization $= 2.0 \times 10^{24}\times 1.5 \times 10^{-23}$
$\Rightarrow 3\times 10$
$\Rightarrow 30 \,AM^{2}$
$\Rightarrow 3\times 10$
$\Rightarrow 30 \,AM^{2}$

Magnetism & Matter
Magnets are used in many devices like electric bells, telephones, radio, loudspeakers, motors, fans, screwdrivers, lifting heavy iron loads, super-fast trains, especially in foreign countries, refrigerators, etc.
Magnetite is the world’s first magnet. This is also called a natural magnet. Though magnets occur naturally, we can also impart magnetic properties to a substance. It would be an artificial magnet in that case.

Some of the properties of the magnetic field lines are:
- The lines and continuous and outside the magnet, the field lines originate from the North pole and terminate at the South pole
- They form closed loops traversing inside the magnet.
- But here the lines seem to originate from the South pole and terminate at the North pole to form closed loops.
- More number of close lines indicate a stronger magnetic field
- The lines do not intersect each other
- The tangent drawn at the field line gives the direction of the field at that point.
