Question

How is the direction of the magnetic field along the axis determined using the right hand?

Options

• Point the fingers along the axis; the thumb points in the direction of current

• Curl the fingers in the direction of current; the thumb points along the magnetic field

• Curl the fingers opposite to the current; the thumb points along the magnetic field

• Point the thumb in the direction of current; the fingers point radially outward

Answer 1

Curl the fingers of your right hand in the direction the current flows around the loop. Your thumb then points in the direction of the magnetic field along the axis.
