Why is soft iron used as the core of the electromagnet in an electric bell ?

Cast iron is used for the production of

Show with the aid of a diagram how a wire is wound on a U-shaped piece of soft iron in order to make it an electromagnet. Complete the circuit diagram and label the poles of the electromagnet.

A battery of emf E and of negligible internal resistance is connected in a L-R circuit as shown in figure. The inductor has a piece of soft iron inside it. When steady state is reached in the piece of soft iron is abruptly pulled out suddenly so that the inductance of the inductor decreases to nL with nlt1 with battery remaining connected. Calculate. a. Current as a function of time assuming t=0 at the instant when piece is pulled. b. the work done to pull out the piece. c. thermal power generated in the circuit as as function of time. d. power supplied by the battery as a function of time. HOW TO PROCEED When the inductance of an inductor is abruptly changed, the flux passing through it remains constant. phi = constant :. Li = constant (L = (phi)/(i))

Explain the following: The north end of a freely suspended magnetic needle gets attracted towards a piece of soft iron placed a little distance away from the needle.

A solenoid of resistance R and inductance L has a piece of soft iron inside it. A battery of emf E and of negligible internal resistance is connected across the solenoid as shown in Fig. At any instant, the piece of soft iron is pulled out suddenly so that inductance of the solenoid decrease to etaL(eta lt 1) with battery remaining connected. The work done to pull out the soft iron piece is

A solenoid of resistance R and inductance L has a piece of soft iron inside it. A battery of emf E and of negligible internal resistance is connected across the solenoid as shown in Fig. At any instant, the piece of soft iron is pulled out suddenly so that inductance of the solenoid decrease to etaL(eta lt 1) with battery remaining connected. Assume t = 0 is the instant when iron piece has been pulled out, the current as a function of time after this is
