Question

Statement I : A compass needle placed near a current-carrying wire will get deflected.

Statement II : A current carrying wire creates magnetic field around it. 

(a) Both the statements are true and Statement II is the correct explanation of Statement I.

(b) Both the statements are true but Statement II is not the correct explanation of Statement I.

(c) Statement I is true, but Statement II is false.

(d) Statement I is false, but Statement II is true.

Answer 1

(a) Both the statements are true and Statement II is the correct explanation of Statement I.

A conducting wire is connected to the poles of battery. The wire is kept above a magnetic needle parallel to it. When current flows through the wire, then needle is deflected. The deflection of needle indicates that with the passage of current in the wire, a magnetic field is established around it.
