Book Free DemoWhy does a magnetic compass needle pointing North and South in the absence of a nearby magnet get deflected when a bar magnet or a current carrying loop is brought near it. Describe some salient features of magnetic lines of field concept.
Current carrying loops as bar magnets which associated magnetic fields. These field lines and cause a deflection in magnetic compass needle by , from its original direction.
Some salient features of magnetic lines of field are as follows:
• Magnetic field has .
• Magnetic field lines emerge from the and enter the .
• The strength of a magnetic field is represented diagrammatically by the .
• At a single point, two values of net field cannot as the field lines .
• If the field lines are parallel and equi-spaced in some region, this means that the field is .
