Arrange the following steps in sequential order to demonstrate the magnetic effect of the elctric cur-rent using magnetic compass. (A) Wind an insulated conducting wire around the magnetic compass such that the axis of the coil is directed along east west direction and con-nect the free ends of the wire to a cell through a switch. (B) Take a magnetic compass. (C ) When current flows through the conducting wire, it behaves as a magnet and deflects the compass needle. (D) When the switch is closed, the magnetic nee-dle in the compass deflects from its initial posi-tion and when the switch is opend, the needle comes back to its initial position.A. BADCB. CBADC. ACBDD. ABCD |

Answer» Correct Answer - A (i) Take a magnetic compass. (ii)Wind an insulated conducting wire aroundthe magnetic compass such that the axis of the coil is directed along east-west direction and con-nect the free ends of the wire to a cell through a switch. (iii) When the switch is closed, the magnetic nec-dle in the compass deflects from its initial posit-tion and when the switch is opened, the needle comes back to its initial position. (iv) When current flows through the conducting wire, it hehaves as a magnet and deflects the compass needle. |
