Final answer:

A paramagnetic material is strongly magnetized in the direction of the magnetic field due to the rotation of atomic magnetic dipoles, which align with the field only while the field is applied and is lost when the field is removed. The correct answer is option 1.

Step-by-step explanation:

When a paramagnetic material is subjected to a magnetizing field, it gets magnetized strongly in the direction of the magnetic field due to the rotation of atomic magnetic dipoles. In the presence of an external magnetic field, paramagnetic materials have their magnetic dipoles align partially with the direction of the applied magnetic field. This is caused by a torque on the dipoles that tends to align them with the field. However, when the magnetic field is removed, the paramagnetic material loses this induced magnetization as the dipoles return to random orientations due to thermal agitation. This behavior is unlike ferromagnetic materials, where the domains grow and realign, and some of the realigned domains can become permanent, giving the material a permanent magnetization.
