2. A student is using a tester made from a magnetic compass needle to test the conductivity of a few materials. There is a strong bar magnet left lying near the tester by mistake. How is it going to affect the working of the tester?
Answers
Answer:
When a magnetic compass is brought close to a current carrying wire there is deflection in the compass due to the formation of magnetic field. The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire. The direction of the magnetic field is perpendicular to the wire.
The deflection increases when the current is increased because the magnitude of the field is directly proportional to the strength of the electric current. That is, stronger the electric current, stronger the magnetic field.
