Two long parallel conductors are placed at right angles to a metre scale at the `2cm` and `6cm` marks, as shown in the figure

They carry currents of `1A` and `3A` respectively. They will produce zero magnetic field at the `(` ignore the earth's magnetic field `)`

Two long parallel conductors are placed at right angles to a metre scale at the 2cm and 6cm marks, They carry currents of 1A and 3A respectively. They will produce zero magnetic field at the ( ignore the earth's magnetic field )

A magnetic field is produced by the two magnets as shown In the figure.The magnetic field is

Find magnetic field at O due to the current carrying conductor as shown in the figure.

Two long wires are placed parallel to each other 10cm apart as shown in figure. The magnetic field at point P is

The force on a current carrying conductor placed parallel to the external magnetic field is

No force acts on a current carrying conductor in a magnetic field when angle between current and magnetic field is

No force acts on a current carrying conductor in a magnetic field when angle between current and magnetic field is

The wire shown in figure carries a current of 32 A . If r = 3.14 cm , the magnetic field at point P will be

Two conductors carrying 1A current each along east to west are held as shown in figure. The magnetic declination at the place is almost zero and angle of dip is 45^@ . The total intensity of earth's magnetic field at the place is 0*32 gauss. Calculate magnetic field at points 0*04m below and above the two conductors.
