A magnetic needle show a deflection when brought close to a current-carrying conductor because
The magnetic needle gets magnetized near a current-carrying conductor
The magnetic needle gets demagnetized near a current-carrying conductor
A magnetic field is produced around the current-carrying conductor
A magnetic needle creates a magnetic field near the wire
A magnetic field is produced around the current-carrying conductor in circular loops
When we bring a magnetic needle near a current carrying conductor it gets deflected. This deflection is an example of:
Which instrument can be used to show that magnetic field exists around a wire carrying current? Why does a compass needle get deflected when brought near a bar magnet? [3 MARKS]
