1.	Assertion: Diamagnetism is universal, it is present in all materials Reason: Field due to induced magnetic moment is opposite to the magnetising field.A. If both assertion and reason are true and reason is the correct explanation of assertion.B. If both assertion and reason are true and reason is not the correct explanation of assertion.C. If assertion is ture but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - A Diamagnetism is when a material acquires amagnetisation in the opposite direction to the applied magnetic field. As a magnetic field will always induce magnetism, diamagnetism will occur in all substances. The magnitude may be small and be overcome by other para or ferromagnetic properties.
