Question

how does the magnetic field lines around a current carrying circular loop look like , explain with the help of Maxwell's thumb rule​

Answer 1

Answer:

If a current carrying conductor is imagined to be held in your right hand such that the thumb points along the direction of current, then the direction of the wrapped car fingers with give the direction of magnetic field lines. Accordingly if current in wire is vertically upward, the magnetic field lines are anticlockwise, while if current in wire is vertically downward, the magnetic field lines are clockwise.

Answer 2

Explanation:

According to Maxwell's right hand thumb rule. Imagine that you are grasping the current carrying wire in your right hand so that your thumb points in the direction of current, then the direction in which your fingers encircle the we will give the direction of magnetic field lines around the wire.

Let AB be the straight wire carrying current in the vertically upward direction from A to B. To find out the direction of the magnetic field lines produced by this current, we imagine that we are grasping the current carrying wire in our right hand as shown in fig. so that our thumb points in the direction of current towards B.

 Now, the direction in which our fingers are folded gives the direction of magnetic field lines. In this case, the direction of magnetic field lines is in the anticlockwise direction.
