(a) How many turns of wire would be on a solenoid carrying a current 4.9 A if the solenoid is 20 cm in diameter, 248 cm long, and the field at the center is 3.3 × 10-3 T?
The magnetic field of a solenoid is the permeability of free space times the number of turns per unit length times the current.
Now How do i find the Number of turns per unit length, Is it Length/Diameter * The field of Center? Thanks
and i know n = N/L so how do i find that
