Electric Current and Magnetic Effects Quiz

The heating effects of electric current are mentioned, as well as the magnetic effect produced by an electric current-carrying wire.

Activity 13.1 is described, where a copper wire is placed between points X and Y in an electric circuit, and a small compass is used to observe the deflection of its needle when current is passed through the wire.

The copper wire (XY) is kept perpendicular to the plane of the paper.

<p>The observation is that the needle of the compass is deflected, indicating the production of a magnetic effect by the electric current through the copper wire.</p> Signup and view all the answers
