Choose the correct option The magnetic field inside a long straight solenoid carrying current a b c d is zero decreases as we move towards its end increases as we move towards its end is the same at all points 13 3 FORCE ON A CURRENT CARRYING C IN A MAGNETIC FIELD We have learnt that an electric current flowing throu produces a magnetic field The field so produced exer magnet placed in the vicinity of the conductor French Marie Ampere 1775 1836 suggested that the magnet an equal and opposite force on the current carrying cond due to a magnetic field acting on a current carrying com demonstrated through the following activity ctivity 13 7 ke a small aluminium rod AB of about 5 cm Using o connecting wires suspend it horizontally from a and as shown in Fig 13 12 ace a strong horse shoe magnet in such a way that e rod lies between the two poles with the magnetic ld directed upwards For this put the north pole of e magnet vertically below and south pole vertically pove the aluminium rod Fig 13 12 onnect the aluminium rod in series with a battery key and a rheostat ow pass a current through the aluminium rod from ad A ned that the rod is
