The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length.
Magnetic Field of a Long Wire.
At sufficiently high magnetic field, such forces will cause the walls of a solenoid to explode outward.
SIMION does not directly or exactly calculate, for example, the magnetic fields generated by wire currents and in particular the fringing effects at the ends of a solenoid coil. Therefore, we may rather utilize an external program (CPO), a formula...
Field of a solenoid. Forces between parallel currents. Magnetic properties result from.
For example in Nuclear Magnetic Resonance (NMR) or Magnetic Resonance Imaging (MRI), the primary, strong, magnetic field must be uniform over the whole sample – or patient in
In the above expression for the magnetic field B, n is the number of turns per unit length, sometimes called the "turns density". The expression is an idealization to an infinite length solenoid, but provides a good approximation to the field of a long solenoid.
You must distinguish between assumptions to prove a theory and real life examples. An infinitely long solenoid (for the theory) would have infinite cross-sectional
