Solution
The correct option is B magnetic effect Whenever a current flows through a conducting wire, there is a magnetic field associated with it. This is called the magnetic effect of electric current. When a compass is brought near this field, there is an interaction between the magnetic fields in the current carrying conductor and the magnetic needle of the compass, which causes the deflection of the magnetic needle.
