Following are the steps to magnetize a steel bar. Arrange them in sequential order.
(A) The end at which current enters in an anticlockwise direction will become the north pole and the other end becomes the south pole.
(B) Keep the steel bar to be magnetized inside a long coil of insulated copper wire.
(C) Pass a strong direct current through the coil for sometime.
(D) The specimen of steel bar will get magnetized.

The correct option is D B C D A
To magnetize a steel bar follow the following steps:
(B) Keep the steel bar to be magnetized inside a long coil of insulated copper wire.
(C) Pass a strong direct current through the coil for some time.
(D) The specimen of the steel bar will get magnetized.
(A) The end at which the current enters in an anticlockwise direction will become the north pole and the other end becomes the south pole.
Hence, the sequential order of steps to magnetize a steel bar is B C D A.
The correct option is (D).
