1.	How can the direction of magnetic field lines at a place be determine❓☺️☺️
Answer» Hi ishika ❤️? Thank you** Thanks you both of you........(hi avi...)☺️ The direction of magnetic field lines at a place can be determined by using a compass needle. A compass needle placed near a magnet gets deflected due to the magnetic force exerted by the magnet. The north end of the needle of the compass indicates the direction of magnetic field at the point where it is placed ?❤️☺️☺️ The direction of a magnetic field at a point is determined by placing a small compass needle. The N - pole of compass indicates the direction of magnetic field at that point.
