three things required for electromagnet are hands eyes ears have fun! lol
A magnetic field, a conductor and movement.
For service sizes of 100 amps and less a #8 bare copper conductor is required.
motor is designed to operate in forward and reverse direction for the purpose of elevator. Phase sequence protection is not required.
A 600 MCM copper conductor with a insulation factor of 75 or 90 degrees C is rated for 420 and 455 amps respectively. To reduce the wire size from a single conductor, a parallel feed of 3/0 can be used.
Yes, ground fault protection for equipment is requiredeven if the neutral will not be used.However, the question implies that it might not be required if there is a neutral. That is not true. With two exceptions, ground fault protection is always required in the US, and it is probably required in other countries as well.The exceptions are the use of an electric cooking range, and an electric clothes dryer. In those cases, the US NEC allows the neutral conductor to also be the ground fault conductor, except for the case where the range or dryer is in a mobile home. In the case of the mobile home, the ground fault conductor and the neutral conductor must be maintained separate and distinct all the way back to the distribution panel.In every other case, including where local code overrides the US NEC's exceptions, it must be understood that ground fault protection (protective earth ground) is not the same as neutral, even though the neutral conductor is grounded.
A person is not required to tip a conductor on a train. Amtrak doesn't discourage tips, but advises customers that tips are not required for either the attendants or the conductor of the train.

To cause electrons to move through a conductor, an electric field is required. This field creates a force that pushes the electrons along the conductor. The strength of the force is determined by the voltage applied across the conductor.
Surge protection is not required in residential environments. However. It is recommended. For commercial, it depends on the city code but usually not required
Hearing protection is typically required at decibel levels of 85 or higher to prevent hearing damage.
A magnetic field, a conductor and movement.
No, dextrose is not a conductor of electricity. It is a simple sugar commonly used as a sweetener in food products and does not possess the properties required to conduct electricity.
For service sizes of 100 amps and less a #8 bare copper conductor is required.
Notification is not required for protection.

Three things required to produce electromotive force (EMF) in an alternator are a magnetic field, a conductor, and relative motion between the magnetic field and the conductor.
