Inductance Coil Material

Assertion (A): Inductance coil are made of copper.
Reason (R): Induced current is more in wire having less resistance.
 
Both A & R are true and the (R) is the correct explanation of the (A)
Both A & R are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Inductance coils are made of copper due to its low resistivity, minimizing energy loss. Low resistance allows more induced current for a given EMF (by \(I = V/R\)). Both Assertion (A) and Reason (R) are true, and R explains A.
