Question

with the help of labeled circuit diagram illustrate the pattern of field lines of the magnetic field around a current carrying straight long conducting wire. how is the right hand thumb rule useful to find the direction of magnetic field associated with a current-carrying conductor​

Answer 1

Answer. Apparatus: A battery (12 V), a variable resistance for a rheostat), an ammeter (0-5 A), a plug key, and a long straight thick copper wire. ... The magnetic field lines are formed in concentric circles around the current carrying conductor and whose centre lies on the wire.
