Question

State righht hand thumb ule to find the direction of magnetic field around a straight conductor carrying current. hw will this magnetic field be affected on a) increasing the current through the conductor b) changing d direction of flow of the current through the conductor?

Answer 1

Explanation:

The right hand thunb rule states that If we hold a current carrying conductor in our right hand such that our thumb represents the direction of the flow of current, then the direction of the folded finger will represent the direction of the magnetic field.

Answer 2

Answer:

If a current carrying conductor is imagined to be held in right hand such that thumb points in direction of current,then curled fingers of hand indicate the direction of magnetic field. If current flows in upward direction then direction will be anticlockwise.
