  • Question 1
    4 / -1

    An infinitely long straight conductor is bent into the shape as shown in the figure. It carries a current of i ampere and the radius of the circular loop is r metre. Then the magnetic induction at its centre will be

  • Question 2
    4 / -1

    A current i ampere flows in a circular arc of wire whose radius is R, which subtends an angle 3π /2 radian at its centre. The magnetic induction B at the centre is

  • Question 3
    4 / -1

    A horizontal overhead power line is at a height of 4m from the ground and carries a current of 100A from east to west. The magnetic field directly below it on the ground is (μ0 = 4π × 10–7 TmA–1)

  • Question 4
    4 / -1

  • Question 5
    4 / -1

    A helium nucleus makes a full rotation in a circle of radius 0.8 metre in two seconds. The value of the magnetic field B at the centre of the circle will be

  • Question 6
    4 / -1

    Consider two straight parallel conductors A and B separated by distance x and carrying individual currents iA and iB respectively. If the two conductors attract each other, it indicates that

  • Question 7
    4 / -1

    The strength of the magnetic field at a point r near a long straight current carrying wire is B. The field at a distance r/2 will be

  • Question 8
    4 / -1

    Field at the centre of a circular coil of radius r, through which a current I flows is

  • Question 9
    4 / -1

    Current ‘I’ is flowing in a conductor shaped as shown in the figure. The radius of the curved part is r and the length of straight portion is very large. The value of the magnetic field at the centre O will be

  • Question 10
    4 / -1

    The magnetic field B with in the solenoid having n turns per metre length and carrying a current of i ampere is given by
