0Case-Based-I: The strength of the magnetic field produced by a current-carrying circular coil (or circular wire) depends on (i) Amount of current flowing through the coil. (ii) Radius of the circular coil. (iii) Number of turns in the circular coil.
A long horizontal power line is carrying a current of \( 100 \mathrm{~A} \) in the east-west direction. The direction of magnetic field at a point \( 1.0 \mathrm{~m} \) below it is
a. south to north
b. north to south
c. east to west
d. west to east
