Question

what is a solidnoid ? ​

Answer 1

Answer:

1.  A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix.

2. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.

3. A solenoid is a device comprised of a coil of wire, the housing, and a moveable plunger (armature).

4. When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in.

5. More simply, a solenoid converts electrical energy into mechanical work.

Answer 2

• The solenoid is used to convert electrical energy into mechanical work.
• The solenoid use coil that is in the form of a tightly packed helix to generate a controlled magnetic field.
• The construction of the coil is arranged in the form to produce a uniform magnetic field when an electric current is passed through it.
• The housing of the coil is usually made of iron or steel, which surrounds the coil concentrating the magnetic field generated by the coil.
• A solenoid is comprised of a moveable plunger (armature).
• The plunger is used to stop the concentration of the magnetic field.
• The length of the coil is greater than its diameter.
