Give a short answer to the question given below.
Mona was doing an experiment with a magnetic compass and a straight current-carrying wire. She observed that as she moved the compass away from the current-carrying wire, the deflection of the compass needle reduced.
Mention one thing that could have changed in the circuit of the wire that could increase the deflection of the needle.
Magnetic field strength is to the current in the wire. So, Mona . the current in the circuit to observe ain the compass needle.
