Q1:

Assertion (A): For a solenoid having N turns, .Reason (R): For all magnetic materials, B increases linearly with I.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:C - A is true but R is false

Increase of B with I is not linear. Hence R is false.
