Assertion : Paramagnetic substances get poorly attracted in magnetic field. Reason : Because magentic dipoles are aligned along external magnetic field weakly.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Paramagnetic substances are weakly attracted to an external magnetic field. When placed in a magnetic field, the magnetic dipoles of the atoms or molecules in paramagnetic materials align themselves in the direction of the external magnetic field, resulting in weak magnetization. This alignment makes paramagnetic substances weakly attracted to the magnetic field. The weak attraction of paramagnetic substances in a magnetic field is due to the fact that the magnetic dipoles within these materials align along the direction of the external magnetic field, but the alignment is relatively weak compared to ferromagnetic materials. This alignment results in weak magnetization and, consequently, weak attraction to the magnetic field. The reason accurately explains why paramagnetic substances are poorly attracted to a magnetic field, making it the correct explanation for the assertion. Therefore, the answer is (1) Both Assertion and Reason are correct, and Reason is the correct explanation of Assertion.
