An electromagnet is not a resistor; they are two different components in an electrical circuit. An electromagnet uses electric current to create a magnetic field, while a resistor resists the flow of electric current, which causes a voltage drop across it.

What does an electromagnet operator do to release metal attached to the electromagnet?
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
What is a mental center of an electromagnet is called?
The mental center of an electromagnet is called the magnetic pole. It is the point on the electromagnet where the magnetic field is concentrated and strongest.
Can quarters stick to a homemade electromagnet?
Yes, quarters can stick to a homemade electromagnet as long as the electromagnet is strong enough to attract the metal in the quarters. The strength of the electromagnet will determine how well it can attract and hold onto the quarters.
What is the name of the rotating electromagnet in an alternator?
The rotating electromagnet in an alternator is called the rotor.
What is the strength of an electromagnet proportional to?
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.
What allows the current to enter the electronromagnet in an electric motor?
The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.
What ll be effect if resistor in snubbing circuit is opened?
The resistor in the snubbing circuit is there to minimize the reverse EMF spike that occurs when a DC inductive load, such as a relay coil or other electromagnet is released. Opening the snubbing circuit will expose the driving circuit to high voltage transients that can damage it.
Which is better a permanent magnet or an electromagnet?
electromagnet

What does an electromagnet operator do to release metal attached to the electromagnet?
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
What does an electromagnet operator do to release metal attached to an electromagnet?

What is a magnet made by electric current?
An electromagnet.
Why electromagnet is used for separating plastic bags?
An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
When was the electromagnet invented?
The electromagnet was invented in the year 1850 by william sturgeon :)
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
