NEET PHYSICS by Pradeep kshetrapal

Magnetic effect of Elect current Lesson no. Phy NEET 12-01

Current I is flowing through a conductotr of shape in the diagram. Linear parts of x the conductor are very long and parallel to X axis while semi-circular part of radius R is in Y-Z plain as shown. The magnetic field at O is 1-2k

The magnetic field at point O is due to current in three different shapes of conductors carrying current. Two are conductors parallel to X axis. Point O is at one end of these conductors 1and 2. 3

(1) Using right hand palm rule, Magnetic field due to current carrying conductor (1) will have direction downward, i.e., n negative z direction. unit vector -k. The magnitude is *. Hence this magnetic field

The magnetic field due to current carrying conductor marked Number 2 will have direction, using right hand palm rule is again downward, unit vector -K The magnitude 1S magnetic field is Hence this Hol

The magnetic field due to current carrying semi circular conductor marked Number 3 in Y-Z plane will have direction, using right hand palm rule is backward is negative x direction, unit vectoir i. The magnitude for full circular col is. magnetic field half circ circular coil is Hen 2R ular coil is 4R

Hence net magnetic field is sum of all the three, i.e. Answer Option (c)

source current I flows from A to B to C to D in sqaure loop

electric current in AB and DA pass through A therefore these two sections do not make any magnetic field at A.
the magnetic field will be formed only by the sections BC and CD both of them at normal distance of 'a'.
Therefore the magnetic field formed will be 2 x mu x i / 2πa . that is "mu x i /πa " tesla.
The direction will be same for both, therefore these magnetic fields are added up to make a total magnetic field.
