Find the magnetic field at point P on the axis of a tightly wound solenoid (helical coil)
Question:
Find the magnetic field at point P on the axis of a tightly wound solenoid (helical coil) consisting of n tums per unit length wrapped around a cylindrical tube of radius a and carrying current I (Fig. 5.25). Express your answer in terms of θ1 and θ2 (it's easiest that way). Consider the tums to be essentially circular, and use the result of Ex. 5.6. What is the field on the axis of an infinite solenoid (infinite in both directions)?
0,7 0₂ P

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
