Question

Quizplus · Accepted Answer

The strength of the enclosed magnetic field is directly proportional to the number of loops in a current-carrying wire. Therefore, as the number of loops is increased, the magnetic field becomes stronger. Option A is incorrect because an increase in the number of loops does not make the magnetic field more spread out. Option C and D are also incorrect as there is no direct correlation between an increase in the number of loops and a weaker current or greater back emf.
