Question

15) a current carrying loop of wire lies flat on a table top. when viewed from above, the current moves around the loop in a counterclockwise sense. for points inside the loop, the magnetic field caused by this current a) circles the loop in a clockwise direction. b) circles the loop in a counterclockwise direction. c) points straight up. d) points straight down. e) is zero.

Answer 1

The correct answer is option C.

Maxwell right hand thumb rule: if we hold a current carrying conductor in our right hand such that the thumb indicates the direction of current then the curling of fingers shows the direction of magnetic field around the conductor.

Here the current is counterclockwise so by use of Maxwell right hand thumb rule the direction of magnetic field is straight up.

Using Fleming right hand rule that States that if the fore-finger, middle finger and the thumb of left hand are stretched mutually perpendicular to each other, such that fore-finger points in the direction of magnetic field, the middle finger points in the direction of the motion of positive charge, then the thumb points to the direction of the force.

So, the current, when viewed from above, seems to move around loop in counterclockwise direction points straight up is because of Maxwell's Thumb Rule.
