When you double the number of windings in a slenoid keepingall other parameters (radius, length, and current) fixed, themagnetic field at the center of the solenoid will A) quadruple B) double C) be reduced to half as much D) triple E) be reduced to one-fourth as much Why??

Explanation / Answer
Magnetic field at the centre ofsolenoid B = 0* N * I / h i.e. B N So doubling no. of turns, magnetic fieldwill be doubled. B)double
