  • Question 1
    4 / -1

    An arc of a circle of radius R subtends an angle π/2 at the centre. It carries a current i. The magnetic field at the centre will be

  • Question 2
    4 / -1

    At a distance of 10 cm from a long straight wire carrying current, the magnetic field is 0.04 T. At the distance of 40 cm, the magnetic field will be

  • Question 3
    4 / -1

    The magnetic induction at any point due to a long straight wire carrying a current is

  • Question 4
    4 / -1

    The expression for magnetic induction inside a solenoid of length L carrying a current I and having N number of turns is

  • Question 5
    4 / -1

    In a current carrying long solenoid, the field produced does not depend upon

  • Question 6
    4 / -1

    A conducting rod of 1 m length and 1 kg mass is suspended by two vertical wires through its ends. An external magnetic field of 2T is applied normal to the rod. Now the current to be passed through the rod so as to make the tension in the wires zero is [Take g = 10 ms–2]

  • Question 7
    4 / -1

    A circular coil \'A\' has a radius R and the current flowing through it is I. Another circular coil ‘B’ has a radius 2R and if 2I is the current flowing through it, then the magnetic fields at the centre of the circular coil are in the ratio of (i.e., BA to BB)

  • Question 8
    4 / -1

    A current I flows along the length of an infinitely long, straight and thin-walled pipe. Then

  • Question 9
    4 / -1

    The magnetic field at the centre of current carrying coil

  • Question 10
    4 / -1

    A straight wire of diameter 0.5 mm carrying a current of 1 A is replaced by another wire of 1 mm diameter carrying the same current. The strength of magnetic field far away is
