Frictional Torque of an Axial Magnetic Suspension
A VERTICAL needle of iron suspended in vacuo by the co-axial field of a solenoid theoretically may have infinitesimal frictional torque against axial rotation. The purpose of the present note is to report an observed value of this frictional torque.
