a. It is inversely proportional to the radius of coil.
Means it decreases on increasing the radius of coil and vice versa .
b. It is directly proportional to the number of turns on wire in the coil . Means it increases on increasing the number of turns on wire in coil and vice versa .
c. It is directly proportional to the current flow in the coil . Means it increases on increasing the current flow in the coil and vice versa
