Question

what is a solenoid? what are the factors that affect the magnitude of magnetic field of solenoid? what is it's main use?​

Answer 1

Strength of a Solenoid

That's because each turn of the wire in the coil has its own magnetic field. Adding more turns to the coil of wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field.

The magnetic field within a solenoid depends upon the current and density of turns. The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills. Iron has a much, much larger permeability than a vacuum

Give its main use. A solenoid is a conducting wire wound around an insulating material. A current carrying solenoid induces a magnetic field around it. ... Solenoids are most commonly used as electromagnets

Answer:

HERE IS YOUR ANSWER:::

A solenoid is a coil of wire with electric current flowing through it. You can see a solenoid in

Any wire with current flowing through it has a magnetic field. However, the magnetic field around a coiled wire is stronger than the magnetic field around a straight wire. That’s because each turn of the wire in the coil has its own magnetic field. Adding more turns to the coil of wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field.

In addition to paintball markers, you can find solenoids in machines ranging from motor vehicles to electric dishwashers.
