Question

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 _________?

• A. 1: n²
• B. n:1
• C. 1: n
• D. 1:1

Answer 1

Answer:

B. n:1

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

• So the ratio is n : 1.
