Question

The direction of the magnetic field lines outside the current carrying solenoid is from

• A. South to North
• B. North to South
• C. East to West
• D. West to East

Hint:

The magnetic field outside a solenoid is directed from the North to the South pole.

Answer 1

The Correct Option is B

When a current flows through a solenoid, it produces a magnetic field that has a definite direction. The magnetic field lines inside the solenoid run from the South to the North pole, while the magnetic field lines outside the solenoid run from the North pole to the South pole. This is the direction of the magnetic field outside a current-carrying solenoid.
