Question

In Part C, you found that the magnetic field contribution at point P, with coordinates (x,y), has magnitude

dB=04Idly[(xa)2+y2]3/2.

What is the behavior of dB in the limiting cases?

x is held constant, while y goes to infinity.

y is held constant, while x goes to infinity.

(a) The magnitude of the field contribution, dB, goes to zero in both cases. (b) The magnitude of the field contribution, dB, goes to infinity in case 1 and zero in case 2. (c) The magnitude of the field contribution, dB, goes to zero in case 1 and infinity in case 2. (d) The magnitude of the field contribution, dB, goes to infinity in both cases.

Explanation / Answer

from the equation of magnetic field, it is evident that

dn varying inverse proportioan to x and y

so

In both cases, dB tends to zero

option A is corrrect
