Draw Circuit Diagram Of A Solenoid To Prepare An Electromagnet. The plunger stops moving when the forces upon it are balanced. A common tractive electromagnet is a uniformly wound solenoid and plunger.
Applying a current to the solenoid applies a force to the plunger and may make it move. When soft iron rod placed inside the solenoid it acts like an electromagnet. On stopping the current flow magnetisation of iron is lost.
The figure shows the magnetic field around a current carrying solenoid.
The use of soft iron in the center increases the magnetic property in the solenoid. On passing current in solenoid coil iron rod begins to behave as a magnet. A common tractive electromagnet is a uniformly wound solenoid and plunger. The solenoid is a coil of wire and the plunger is made of a material such as soft iron.
