Solenoid
A Solenoid is a wire wrapped around a
metallic core which creates a magnetic field on transfer
of current to it. Solenoids can create controlled
magnetic fields and can be used as electromagnets.
The magnetic field inside a solenoid
is given by:
B=unI=uNI/h
where u=(4*22/7)*10 to power -7
henries per meter.
B is the magnetic field magnitude in
teslas, n is the number of turns per meter, I is the
current in amperes, N is number of turns, h is the
length of the solenoid in meters
Such coils, called
solenoids, have an enormous number of practical
applications. The field can be greatly strengthened by
the addition of an iron core

solenoid with a uniform magnetic field? Build a
solenoid by adding current loops to the simulation
