Harvard Mark III Wikipedia

The Mark III used nine magnetic drums (one of the first computers to do so). One drum could contain 4,000 instructions and has an access time of 4,400 microseconds; thus it was a stored-program computer. The arithmetic unit could access two other drums one contained 150 words of constants and the other contained 200 words of variables.

Electromagnetic Brakes How they work

This magnetic attraction pulls the armature in contact with the brake field face. The friction and the strength of the magnetic field, is what causes the rotational motion to stop. Almost all of the torque comes from the magnetic attraction and coefficient of friction between the steel of the armature and the steel of the rotor or brake field.
