Question

properties of solenoid??

Answer 1

1. a long tightly wound helical coil insulated metallic wire is called solenoid
2. the magnetic field produce inside the solenoid( also called core of solenoid ) is Constant
3. a circular solenoid is called toroid
4. the strength of magnetic field increase if current flowing in solenoid increase
5. current flow in the anticlockwise direction then that end is north pole to south

Answer 2

The properties of solenoid are
- its an electromagnet
- current is uniformed inside
-outside current is not uniformed
- its circlular ends produces attraction and repulsion .
