A straight conductor AB is held parallel to a freely suspended magnetic needle, such that the current flows from A to B. Why dose the magentic needle show deflection?

Due to the magnetic field created around the magnetic needle by the current carrying conductor

Solution

The correct option is A
Due to the magnetic field created around the magnetic needle by the current carrying conductor

When current passes through a conductor it creates a magnetic field around it which is in circular loops and this magnetic field is responsible for deflection of the magnetic needle.
