Question

at a neutral point the resultant charge of a magnetic field is
a) current
b) uniform
c) non uniform
d) none of these​

Answer 1

Magnetic fields, including those used in electromagnets, surround and are formed by magnetized material and by moving electrical charges (currents). A neutral point of any magnet is defined as a point at which the resultant magnetic field is always zero.

So, the correct answer is CURRENT.
