A wire in the form of a tightly wound solenoid is connected to a DC source, and carries a current. If the coil is stretched so that there are gaps between successive elements of the spiral coil, will the current increase or decrease?

A solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, will the current increase or decrease?
There are many types of spring. Important among these are helical and spiral springs as shown in figure.(a) (b) Usually, we assume that the springs are massless. Therefore, work done is stored in the spring in the form of elastic potential energy of the spring. Thus, potential energy of a spring is the energy associated with the state of compression or expansion of an elastic spring.The potential energy of a spring increases by `15 J` when stretched by 3 cm. If it is stretched by 4 cm, the increase in potential energy
