Q.

Two wires each carrying a steady current I are shown in four configurations in Column – I. Some of the resulting effects are described in Column – II. Match the statements in Column – I with the statements in Column – II :
 

 Column – I Column – II
A)

Point P is situated midway (p) Between the wires 

Question Image

 

P)The magnetic fields (B) at P due to the current in the wires are in the same direction
B)

Point P is situated at the mid-point of the line joining the centres of the circular wires, which have same radii 

Question Image


 

Q)The magnetic fields (B) at P due to the currents in the wires are in opposite directions

A) 

Question Image

In this case the magnetic field due to the top wire and the bottom wire acts in opposite directions and cancel out. Therefore magnetic field at P is zero.

B)

Question Image

Here the magnetic fields due to both the wires will be towards right.

C)

Question Image

Magnetic field at P is in opposite direction due to two wires and has same magnitude. So net magnetic field is zero at P. 

D) 

Question Image

Magnetic field due to the inner circle will be out of the plane and due to outer circle is into the plane. Magnetic field will be in opposite direction but magnitude will be non zero.
