Magnetic field: this very simple electric motor is called a homopolar motor because the magnetic field does not change direction or strength. With only three parts, it is probably the simplest motor you can possibly make.
The magnetic field in the shielding material is related to the electric field, the smallest detectable field strengths (using sensitive field probes) are on the order.
