Answer:
a cylindrical coil of wire acting as a magnet when carrying electric current.
Explanation:
Consider a circular element of thickness dx of the solenoid at a distance x from its centre. The magnitude of the total field is obtained by integrating over all the elements from x = −l to x = +l. This is the expression for magnetic field due to a solenoid on the axial line at a distance r from the centre.
