1.	Describe the experiment to explain that force acts on a current carrying conductor in presence of a magnetic field.
Answer» Solution :Materials : Flexible copper wire, stand, electric cell, a horse shoe magnet with a strong magnetic field. Procedure : Using the stand, fix the copper wire so that it passes through the poles of the horse shoe magnet. CONNECT the wire to the BATTERY to complete the circuit Observation :Whenever a current is not FLOWING through the wire, it remains straight (POSITION A). 2. When the current FLOWS from top to bottom, the wire bends and comes into position C. 3. If the current direction is reversed, i.e. it flows from the bottom to the top end, the wire bends but comes in the position B. 4. This means the direction of the force on the wire is perpendicular to both the magnetic field and the direction of the current. 5. Here, the direction of magnetic field is from N to S, (H). Conclusion : 1. In this experiment, it is noted that whenever current flows through a conductor in the presence of magnetic field a force is exerted on the conductor. 2. If the direction of the current is reversed, the direction of the force also gets reversed. 3. The direction of this force depends on both the direction of the current and the direction of the magnetic field.
