A current carrying conductor is held in exactly vertical direction. In order to produce a clockwise magnetic field around the conductor, the current should be passed in the conductor:
From top to bottom
From left to right
From bottom to top
From right to left
Who has stated the Right hand Thumb Rule?

Ampere
No force acts on a current carrying conductor when it is placed-
perpendicular to the magnetic field
parallel to the magnetic field
far away from the magnetic field
inside a magnetic field
Which of the following statement is not correct about the magnetic field?
Magnetic field lines form a continuous closed curve.
Magnetic field line do not interest each other.
Direction of tangent at any point on the magnetic field line curve gives the direction of magnetic field at that point.
Outside the magnet, magnetic field lines go from South to North pole of the magnet.
The strength of magnetic field around a current carrying conductor is
inversely proportional to the current but directly proportional to the square of the distance from wire
directly proportional to the current and inversely proportional to the distance from wire.
directly proportional to the distance and inversely proportional to the current
directly proportional to the current but inversely proportional the square of the distance from wire
