The ratio of the field due to a current-carrying circular coil of n turns to the field due to a single circular loop of the same radius carrying the same current is _________?

A1: n²

Bn:1

C1: n

D1:1

Answer:

B. n:1

Read Explanation:

  • The magnetic field strength is directly proportional to the number of turns (n)

  • So the ratio is n : 1.
