Magnetic field due to solenoid

Answers

A solenoid is a cylindrical coil of wire acting as a magnet when carrying electric current. The direction of the field can be determined using a simple rule stated as follows “if the coil (solenoid) is viewed from one end and the current flows in an anticlockwise direction at that end, then that end is the North Pole. If the current flows in a clockwise direction, then that end is the South Pole”.
