UR unes show the direction (at every point) which a small magnetised needle takes up (at that point). Do the magnetic field lines also represent the lines of force of a moving charged particle at every point? (b) If magnetic monopoles existed, how would Gauss's law of magnetism be modified? (c) Does a bar magnet exert a torque on itself due to its own field? Does one element of a current carrying wire exert a force on another element of the same wire? (d) Magnetic field arises due to charges in motion. Can a system have magnetic moment even though its net charge is zero? (e) Magnetic force is always normal to the velocity of a charge and therefore does no work. An iron nail held near a magnet, when released, increases its kinetic energy as it moves to cling to the magnet. What monc je resnonsihle for this increase in kinetic energy if not the magnetic field?

Does a bar magnet exert a torque on itself due to its own field ? Does one element of a curren-carrying wire exert a force on another element of the same wire ?

If magnetic monpole existed, how would Gauss law of magnetism be modified?

If magnetic monopoles existed, how would tha Gauss's law of magnetism be modified ?

(c) If magnetic monopoles existed, how would the Gauss's law of magnetism be modified ?

(a) Magnetic field lines show the directions (at every point) which a small magnetised needle takes up (at that point). Do the magnetic field lines also represent the lines of force of a moving charged particle at every point? (b) Magnetic field lines can be entirely confined within the core of a toroid, but not within a straight solenoid. Why? (c) If magnetic monopoles existed, how would Gauss's law of magnetism be modified? (d) Does a bar magnet exert a torque on itself due to its own field? Does one element of a current carrying wire exert a force on another element of the same wire? (e) Magnetic field arises due to charges in motion. Can a system have magnetic moment even though its net charge is zero? (f) Magnetic force is always normal to the velocity of a charge and therefore does no work. An iron nail held near a magnet, when released, increases its kinetic energy as it moves to cling to the magnet. What agency is responsible for this increase in kinetic energy if not the magnetic field?

A: A bar magnet does not exert a torque on itself due to its own field. R: One element of a current-carrying non-straight wire exert a force on another element of the same wire.

A: A bar magnet does not exert a torque on itself due to its own field. R: One element of a current-carrying non-straight wire exert a force on another element of the same wire.

If magnetic monopoles would have existed.how would the Gauss' law of magnetism be modified?

(a) Magnetic field lines show the direction (at every point) along which a small magnetised needle aligns at the point). Do the magnetic field lines also represent the lines of force on a moving charged particle at every point?

(c) If magnetic monopoles existed, how would the Gauss's law of magnetism be modified? (d) Does a bar magnet exert a torque on itsell due to its own field? Does one element of a current-carrying wire exert a force on another element of the same wtre? (e) Magnetic field arises due to charges in motion. Can a system have magnetic moments even though its net charge is zero?
