Question

Write Maxwell's right-hand thumb rule. What should be the angle between the magnetic field and current?

Answer 1

Maxwell's right-hand thumb rule:

1. If we hold a current-carrying conductor in the right hand, the thumb points the direction towards the current. Then wrap the fingers around the conductor, and the finger gives the direction of the magnetic field lines.
2. The right-hand thumb rule gives the direction of the magnetic field or current.
3. The angle between the magnetic field and current should be ${90}^{\mathrm{o}}$.
