What is solenoid draw the pattern of magnetic field?
Answers
Answer:
BECAUSE MAGNETIC FILED LINES TERMINATED BOTH FROM NORTH TO SOUTH POLE
Answer:Hi!!!
Your answer is ;-
A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside.
Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.
The magnetic field within a solenoid depends upon the current and density of turns.
In order to estimate roughly the force with which a solenoid pulls on ferromagnetic rods placed near it, one can use the change in magnetic field energy as the rod is inserted into the solenoid. The force is roughly
Force on rod = change in magnetic field energy ÷ distance rod moves into solenoid
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.
Even small solenoids can exert forces of a few newtons.
